Help End Prison Gerrymandering Prison gerrymandering funnels political power away from urban communities to legislators who have prisons in their (often white, rural) districts. More than two decades ago, the Prison Policy Initiative put numbers on the problem and sparked the movement to end prison gerrymandering.

Can you help us continue the fight? Thank you.

Columbia County is about to reapportion political power, free from the distortion caused by prison gerrymandering.

by Leah Sakala, September 5, 2013

Register-Star thumbnail

An article in today’s Register-Star reports that Columbia County, New York is working on reapportioning local political power to comply with the Supreme Court’s requirement that every voter have a right to equal say in government affairs. Thanks to a 2010 historic voting rights law that outlawed prison gerrymandering in New York, this time the county’s reapportionment process won’t be undermined by the Census Bureau’s prison miscount.

Before, Columbia County based local apportionment on total Census Bureau population data, which includes all the people who are locked up in the Hudson Correctional Facility. That gave the community members who live in the Ward that contains the prison an unfair advantage at the ballot box. But no more.

The new law solved this electoral quandary by requiring that incarcerated people in New York be counted at their home addresses for redistricting purposes. This means that Columbia County’s new apportionment scheme will be based on number of people who are actual Columbia County residents, which, at the end of the day, is what fair electoral systems are all about.

County Supervisor Ellen Thurston’s ward contains the Hudson prison, so she’ll be losing her extra political sway now that incarcerated people are counted in their home communities. But she knows that ending prison gerrymandering was the right thing to do:

Despite the loss of population, Thurston said she agreed with the state law.

“I think it’s fair that [incarcerated people] be counted in their hometown,” she said.

Prison gerrymandering no longer distorts New York’s state legislative districts. When the last of New York’s local governments, such as the City of Rome, finish up reapportioning local electoral power to comply with the law as well, the state will be completely free from the scourge of prison gerrymandering.


A column in The Vindicator shows how prison gerrymandering could undermine local democracy in a Ohio city.

by Leah Sakala, August 16, 2013

The Vindicator thumbnailCheck out David Skolnick’s must-read column in today’s issue of The Vindicator about how the Youngstown, Ohio city council can avoid prison gerrymandering.

As he explains:

The census considers prisoners to be residents of where they are incarcerated, even though except for some at the county jail, none of them can vote, and members of council don’t really represent them…

When officials with the Prison Policy Initiative read in The Vindicator about Youngstown City Council redistricting the seven wards to make each more equitable, they pointed out that counting inmates doesn’t really balance the populations in the wards.

Mr. Skolnick says that our concerns “merits serious discussion.” But will the Youngstown city council heed our advice and join the 220+ other local governments that refuse to let the Census Bureau’s prison count skew local democracy? We’ll see.


To draw new wards that are fair and equal the city council must exclude the prison counts from the redistricting data.

by Leah Sakala, August 13, 2013

The Vindicator

As The Vindicator recently reported, the city council of Youngstown, Ohio is working on redrawing the city ward boundaries for the first time in 30 years. Youngstown voters overwhelmingly approved a ballot measure to require the the seven city wards to be redrawn to comply with the constitutional guarantee of “one person, one vote.” But in order to draw fair and equal wards, the city council must take one more simple step: exclude the state and federal prison counts from the redistricting data.

The problem is that the 2010 Census counted 66,982 people in Youngstown, but more than 3,000 of those people are behind bars in the prisons or jail that are located within city limits. If the city councilors decide to draw new wards based on the data as-is, they could end up drawing a “prison gerrymandered” district where more than a quarter of the “population” is made up of non-voting incarcerated people who aren’t even local residents.

As I pointed out in my letter to the editor published on Sunday in The Vindicator, when state or local districts are based on unadjusted Census Bureau data, people who live near big prisons get an unfair political boost and everyone else’s votes are diluted.

Fortunately, after we reached out to city officials to give them a heads up, it looks like they’re paying attention. As the council’s redistricting process moves forward, the councilors should follow the lead of Lima, Ohio and more than 200 other local governments around the country that refuse to let their local democracy be compromised by the Census Bureau’s prison counts.

The Youngstown city council is planning on wrapping up the redistricting process by the end of the year, so stay tuned!


"The city is still counting prisoners as population... it’s wrong to include them when voter representation is determined."

by Leah Sakala, July 15, 2013

The Utica Observer-Dispatch published a strong editorial calling on the City of Rome to comply with the New York law banning prison gerrymandering by updating its city council lines:

Our view: Free prisoners — from voting data

thumbnail of Observer Dispatch editorialRome needs to get rid of its prisoners in the Second Ward — at least on paper. More than two years after a state law passed requiring municipalities to account for prisoners when redrawing legislative lines, nothing has happened. The city is still counting prisoners as population, and while that might work for census purposes, it’s wrong to include them when voter representation is determined.

That must change. In 2011, 2,083 of the second ward’s roughly 5,000 residents were prisoners in the Oneida and Mohawk correctional facilities. But they do not vote or participate in city affairs.

The 2010 law provided two options: Either remove prisoners from the counts altogether or to use new state data that reallocates them to their hometowns. Either option is fair. What’s not fair is the status quo. Some believe lower numbers would affect state aid, but Peter Wagner, executive director of the nonprofit Prison Policy Initiative, says that’s not so.

Rome is considering redrawing ward lines. It should exclude the prisoners. Putting them in the mix is a grave injustice to taxpaying Romans.


Rome (NY) stalls on redistricting, prolonging prison gerrymandering.

by Aleks Kajstura, July 8, 2013

Today, a headline in the Utica Observer-Dispatch declared: “Rome still counting prisoners in legislative districts”. Several years after New York outlawed prison gerrymandering, the city of Rome, in Oneida County, New York, is still dragging its feet, clinging to old ward lines that give extra representation to the residents of the ward with the prison. As we’ve been watching the state of New York and its local governments draw fairer districts without prison gerrymandering, we were shocked to see Rome — the most dramatic example of prison gerrymandering in the state — fall behind.

thumbnail of Observer Dispatch article

The 2000-era data underlying the current districts tabulated the people incarcerated at the Oneida and Mohawk state correctional facilities as if they were residents of Rome. As a result, half of Ward 2 was made up of incarcerated people; that gave every actual resident of Ward 2 twice as much voting power as any other resident of the city. And the 13-year-old data still haunts the ward boundaries today, diluting votes, and democracy in the city.

The 2010 Census again tabulated the people incarcerated in the two state correctional facilities as if they were residents of the city. (The Oneida facility has since closed, depriving Ward 2 of even some of its phantom constituents.) But, in 2010, New York State passed a law (Part XX of Chapter 57 of the Laws of 2010) requiring cities like Rome to either exclude the prison population form redistricting data, or use the redistricting data published by LATFOR (New York’s Legislative Task Force on Demographic Research and Reapportionment), which counts incarcerated people at their home addresses. The data for both options has been available for almost two years.

The most shocking part of the article was Councilman John Mortise (Ward 2) throwing both state and federal law into the wind, and proposing to eventually divide the wards equally, by land area.

Luckily, that’s not how it works. The citizens of Rome are going to get democracy, but the question is: how long they’ll have to wait for it to arrive.


The Census Bureau’s prison miscount is indeed a complication to improving Section 4, but it’s neither an insurmountable barrier nor a permanent one.

by Peter Wagner, June 26, 2013

Yesterday, the Supreme Court struck down Section 4 of the Voting Rights Act, the section that determines which state and local governments must, under Section 5, receive federal approval before changing their voting laws. By striking down Section 4’s criteria, the Court has, at least temporarily, made Section 5 irrelevant.

The solution is, as the Court said, for Congress to develop a new set of criteria to determine which jurisdictions have to report to the federal government under Section 5. In a New York Times article about various proposals for a new formula, we noticed that one proposal – although probably the least likely to be used — is seriously skewed by the Census Bureau’s outdated practice of tabulating incarcerated people as if they were residents of correctional facilities. (Under most state laws, people in prison remain legal residents of their pre-incarceration residences.) This creates big problems at redistricting time, because it transfers political clout to the areas that host prisons and dilutes the votes cast in every other district. We call it “prison gerrymandering,” and that’s usually where our focus on the implications of Census Bureau’s prison miscount stops.

Although we’ve occasionally written about how the Census Bureau’s prison miscount distorts the demographic profiles of communities, we usually choose to focus on the larger harm to voting rights rather than just demographics. But the need for a new formula for Section 4 changes that calculus a bit.

The New York Times published this map with 2012 data showing who would be covered by Section 4 if it were changed to apply to state and counties where the estimated citizen turnout was below 50%:

New York Times map of voter turnout

This map looked eerily familiar to me; I recognized many of these counties, especially in Colorado, Montana, New York, Florida, Oregon, California, Nevada, Arizona, and Michigan, as places that I know have large prisons. Northern New York and Eastern Oregon were the dead giveaways that made me realize the similarities between this map and one from my 2004 report with Rose Heyer, Too Big to Ignore: How Counting People in Prisons Distorted Census 2000:

Map showing percent incarcerated by county

In some counties, inflating the reported population by including non-voting incarcerated people who come from other parts of the state could slightly change the portion of the total population that turns out to vote in a given election. But in other sparsely populated rural counties, massive prisons can radically change the apparent voter turnout. In our study of the 2000 Census, we found 21 counties where more than 21% of the population was incarcerated. Less poetically, we found 91 counties where more than 10% of the population was incarcerated. These weren’t necessarily the most punitive places, just the places where the Census Bureau was the least able to easily tell you something useful about the county because information about the actual residents was skewed by information about the prison population. The data used to make the New York Times‘s map isn’t publicly accessible, so I can’t do my own calculations, but I’d expect that what appears to be a pattern of voting suppression in upstate New York is actually just the Census’s reflection of rural prison construction.

I don’t have a position on which formula Congress should use to update Section 4 of the Voting Rights Act. There are certainly lots of ways to define which communities need Section 5 oversight, but clumsy approaches that single out rural counties with prisons as vote suppressors aren’t good solutions. (This is especially true given that the decision to bar people in prison from voting is a state decision, not a local one.)

The Census Bureau’s prison miscount is indeed a complication to improving Section 4, but it’s neither an insurmountable barrier nor a permanent one:

  1. It is in fact possible to calculate voting turnout for rural counties in ways that are not skewed by the Census Bureau’s prison miscount. (Hint: See Summary File 1, Table P42 for the numbers to remove from the denominator. We’ve also done more sophisticated adjustments to the race and ethnicity data. Contact us for more on that.)
  2. If the Census Bureau would agree to count the 1% of the adult population that is incarcerated in the correct location in the decennial census, this kind of problem wouldn’t ever come up. The Census is an important tool, and improving the prison count would make that data far more useful for all kinds of electoral purposes.

Kentucky Senator Thayer (R) had some harsh words about prison gerrymandering in the state.

by Aleks Kajstura, June 5, 2013

Senator Thayer (R – Grant, Kenton, Owen, and Scott Counties) had some harsh words about prison gerrymandering in Kentucky: “the core of redistricting… is ‘one person, one vote’ and this [prison gerrymandering] is flying in the face of that.” Senator Thayer, then-co-chair of Kentucky Task Force on Elections, Constitutional Amendments, and Intergovernmental Affairs, was one of the most vocal opponents of prison gerrymandering at a November 27, 2012 hearing on BR 219, an act to end prison gerrymandering in Kentucky, introduced by co-chair Representative Owens (D – Jefferson County). I just had the opportunity to review the tape recording of the hearing and found a lively discussion of prison gerrymandering.

Kentucky is one of the few states still redistricting their state legislature after the 2010 Census, and Task Force members from across the aisle joined the Senator in expressing dissatisfaction with the way prisons skew representation in the Kentucky legislature.

Although we usually explain the effects of prison gerrymandering in terms of how if affects a resident’s vote, Senator Thayer offers another perspective: “Looking at it from our perspective as candidates, those who represent districts with prison population actually have to work to get fewer votes for re-election when those of us who live in districts where we have a lot of people but no prisons.”

Senator Thayer cut right to the chase in pointing to the Census Bureau’s role in the problem, saying that “it seems like we, here at the state level, have a mess to clean up created by the federal government.” As the Census Bureau drags their feet, and Kentucky takes up redistricting again in the new session, the state should take the opportunity to address prison gerrymandering.


The Bureau is aware of our organizations' concerns about prison gerrymandering, but side-stepped our request to prioritize developing a solution.

by Peter Wagner, May 17, 2013

Acting Director explains Bureau’s immediate priorities but sidesteps request to prioritize developing a solution to prison gerrymandering

The Census Bureau has replied to the February 14 letter from 210 organizations urging it to make “developing a methodology to tabulate incarcerated people at their home addresses a near-term priority.” I wanted to share the Census Bureau’s response, along with some of my thoughts about it. In a nutshell, the Bureau is aware of our organizations’ concerns about prison gerrymandering, but side-stepped our request to prioritize developing a solution.

Our coalition letter was intended to inform the Census Bureau that a diverse group of stakeholders wants the agency to start planning how to tabulate incarcerated people at home. In our view, the Bureau needs to recognize that the prison count is the largest and most visible failing with regard to where it tabulates people in the decennial enumeration, and start researching solutions now.

But in his reply to our letter, Acting Director Thomas Mesenbourg explained that the Bureau would not focus, in the near term, specifically on the issue of where the census tabulates incarcerated people. Instead, Mr. Mesenbourg described how researching solutions to prison gerrymandering fits into the Bureau’s current longer-term agenda: as one part of a much broader inquiry on residence rules that will take place — budget permitting — in Fiscal Year 2015. That falls far short of what we asked for, but the clarity of the Bureau’s response is helpful in determining our next steps. I wanted to share some further thoughts about the Acting Director’s letter, and some ideas moving forward.

The Bureau’s immediate priorities

The reply letter nicely summarizes the overall challenges the Bureau faces to maintain the quality of the decennial census while controlling costs, listing the four areas where the Bureau is currently focusing its energy. The Bureau then gives an update on an important moving target: exactly when research on improving the group quarters count could take place.

The problem of prison gerrymandering may be one of the most glaring defects in the Census, but, as the reply letter explains, the Bureau is instead prioritizing work on fundamental changes in the structure and operations of the decennial census in order to trim several billion dollars from the cost. I can see how the Census Bureau might, in contrast, view improving the tabulation of just one group of people — no matter how glaring the problem — as a lower priority.

The strategic challenge for our movement is not the complexity of the research required, it is the timing. Improving how incarcerated people are counted is not rocket science, but it does requires diligent planning. After all, people in prisons and jails are the only population in the country that the government counts multiple times every day. The Bureau needs sufficient time to find solutions to legitimate questions about the best way to collect and process these data.

In the reply letter, the Acting Director says that “research [on] other aspects” of the 2020 Census can begin only after the “high-level design” is completed, in 2015. This delay is potentially, though not definitively, problematic for the efforts to end prison gerrymandering by the next redistricting cycle. 2015 isn’t necessarily too late to begin researching how to tabulate incarcerated people at home in 2020, but it leaves a very small window of opportunity because the details of the 2020 Census will be locked in place long before 2020 rolls around. Unless the Bureau articulates a clear intent to pursue methods to tabulate incarcerated people at their homes of record, the passage of time will leave the Bureau will no choice but to continue its outdated methodology in the 2020 Census.

No clear statement on research priorities

While our letter acknowledged the Bureau’s budgetary challenges, our letter asked the Bureau to include ending prison gerrymandering in its near-term priorities. Unfortunately, the reply did not address the matter of priorities directly or explain why the Bureau can’t begin the process of planning improved ways to tabulate incarcerated people while it completes redesigning other components of the Census. Supporters of the constitutional principle of “One Person, One Vote” should be very concerned by the prospect of relegating the question of how incarcerated people are counted — the most visible fairness flaw in the decennial census — to only one piece of a larger research question that will not start until 2015, budget permitting.

The Role of Congress and the Bureau’s fear of controversy

The Census Bureau has the power to end prison gerrymandering, and the letter’s summary of the Bureau’s residence rules methodology since the Census Act of 1790 supports our position that the Bureau has the authority to revise its methodology to keep pace with social and demographic change. The question of where to tabulate incarcerated people is clearly within the Bureau’s discretion, but, as the Acting Director noted, the Bureau looks to Congress before making any changes that could be vulnerable to criticism.

Unfortunately, this fear of political controversy may be leading the Census Bureau to prioritize the consequences of changing the residence rule over the consequences of the status quo for the health of our democracy. The Acting Director’s one nod to the rule’s larger implications for democracy is that “[w]e understand fully the major impact on different states as well as counties and municipalities … [during] redistricting if we considered changing the residence rule” (emphasis added). Ironically, the Bureau’s own commissioned experts at the National Research Council of The National Academies had no such problem acknowledging the need for change, noting the current rule’s detrimental impact on democracy. During last decade’s review of the residence rules, the expert panel concluded that “[t]he evidence of political inequities in redistricting that can arise due to the counting of prisoners at the prison location is compelling.”

Even as the Acting Director’s reply letter stating that the Bureau “must inform and try to ascertain the will of the Congress on such a major change” was in the mail to me, the Census Bureau received evidence of congressional concern about the Bureau’s current policy. On April 1, 2013, 18 members of Congress wrote to the Bureau about why properly tabulating incarcerated people is important to state and local governments. They wrote, “We… urge the Census Bureau to take the steps necessary to ensure that Census 2020 counts prisoners at their home addresses to assist state and local governments in accurately representing these populations.”

Finally, the Bureau’s concern that “major change … regarding apportionment” necessitates the assent of Congress is a red herring. Congressional apportionment is unlikely to be affected by tabulating incarcerated people at home because most people do not cross state lines when they are incarcerated.

Moving forward

But beyond congressional weigh-in, the Census Bureau wants to get the input of as many stakeholders as possible before making a change to where incarcerated populations are counted. That is yet another reason why the comparatively straightforward activity of improving where incarcerated people are tabulated needs to start sooner rather than later.

Finally, the Bureau’s reply is a good indication of how much work we have left to do to establish why it is necessary to change where incarcerated people are tabulated. The letter, in my view, both understates the impact of prison gerrymandering on local and state governments and undervalues the Bureau’s own significant efforts to help those local governments by producing the Advance Group Quarters Summary File. This file, which the Bureau produced for the first time ever in 2010, was incredibly helpful to many state and local governments that wanted to eliminate, minimize or at least consider avoiding the effects of prison gerrymandering.

The driving reason to address prison gerrymandering is its dramatic impact on state and local governments. It is easy to understand why the Census Bureau, as a federal agency, might prioritize questions of congressional apportionment over state legislative, and even county/municipal, redistricting. But congressional apportionment is not the primary concern because prison populations are rarely significant in determining a 700,000 person Congressional district. The real impact of prison gerrymandering is at the state legislative level and, especially, at the county/municipal level. The smaller the legislative district, the more likely it is that a single prison could make up a large part, or even an actual majority, of the district. Taken together, prison gerrymandering’s impact is pervasive, and the overwhelming majority of the nation will benefit in at least one way when the practice comes to an end. As general messaging point, our movement needs to ensure that the real reasons to end prison gerrymandering remain in focus.

Moving forward, it is imperative that the Census Bureau continue to hear from all of its stakeholders — at the federal, state and local levels — that now is the time to address the problem of prison gerrymandering in order to resolve the problem by 2020. We shouldn’t have to wait until 2030 to fix such an obvious flaw in the Census Bureau’s methodology that compromises state and local democracy around the nation.


A handful of communities avoid prison gerrymandering and redistricting.

by Aleks Kajstura, May 16, 2013

We’ve been monitoring how counties and municipalities across the nation have addressed prison gerrymandering. We found that the vast majority of communities (over 200) with both a large correctional facility and a district form of government avoided prison gerrymandering.

The communities employ different techniques but they all lead to the same result: districts are drawn as if the Census Bureau had not counted the incarcerated population in that community. Some communities adjust the Census figures, some “overpopulate” the district with the prison, and some cut holes in the maps around the prison. But a handful of communities avoid prison gerrymandering by avoiding redistricting.

Communities can comply with the principle of “one person, one vote” without redistricting, if their population has not changed. For example, a city whose population hasn’t changed from one decade to another does not need to redistrict as long as the population within each district also remained equal.

We’ve discovered a number of places that have chosen not to redistrict because the only significant change in the total Census population is the correctional population:

  • Robinson City, Illinois saw population growth in the 2010 Census as a result of annexing the Robinson Correctional Center. The city didn’t redistrict after the 2010 Census, and really doesn’t have to. The total Census population has radically changed, but the resident population is basically the same. The old districts, drawn before the Census allocated the prison to the city, continue to fairly distribute political power to the city’s residents.
  • Post City, Texas had a total population change of 1672 (a 36% increase) between the 2000 and 2010 censuses. But the city didn’t include the incarcerated population at the federal Giles W. Dalby Correctional Institution in its redistricting data when it redrew the city council districts in 2001, so when the prison’s population expanded from 371 in the year 2000 to 1,995 by the 2010 census, Post’s districts remained equally apportioned.
  • The Town of Enfield, Connecticut also excluded the incarcerated populations at the Robinson Correctional Institution, Willard-Cybulski Correctional Institution, and Enfield Correctional Institution when it redistricted in 2010. Then after the 2010 Census, Enfield concluded that there was no significant population change and did not redistrict.
  • Karnes City, Texas had a 12% change in total population reported by the Census, but most of that was due to a decrease in the incarcerated population at the Karnes County Correctional Center. Not counting the incarnated population, the town only lost 196 actual residents.
  • Pike County, Missouri kept their district lines the same when the 2010 Census revealed little change in population. The County’s districts remain unskewed by the prison population at Missouri’s Northeast Correction Center.

So while these communities technically didn’t redistrict after the 2010 Census, they have rejected the Census Bureau’s prison counts and avoided prison gerrymandering.


Now that most state and local redistricting efforts have come to a close, it's clear that this data has been central to our recent advocacy efforts.

by Peter Wagner and Aleks Kajstura, May 16, 2013

Two years ago, working within a tight timeframe, the Census Bureau released a new data product that made huge progress towards helping state and local governments avoid prison gerrymandering: the Advance Group Quarters Summary File.

This data, which identified the census blocks that contain group quarters such as correctional facilities, was released early so that state and local redistricting bodies could choose to use this information to draw fair districts.

Now that most state and local redistricting efforts have come to a close, we thought it would be useful to give an overview of how central this data has been to our recent advocacy efforts:

To make the file easier to use, within hours of the file’s release we:

  • Prepared an ESRI point shapefile and Google KML files with the entire database, and for the correctional blocks, included links to our database of annotations.
  • Released a web version (google maps, and tables) of the correctional portions of the file.

To make the file more informative, we:

  • Labeled 80% of the blocks by facility name and type. (We have labeled 94% of blocks containing more than 100 people in a correctional facility. The smaller halfway houses and other facilities are much harder to identify and less relevant in the redistricting context.)
  • When Summary File 1 was available, developed a methodology to determine the race/ethnicity (9 combinations) of the correctional population in each block for all but 4 blocks and then made this data available online.
  • Reported the gender and age (<18, 18-65, 65+) of the correctional population for each block.
  • Reported how the Census Bureau classified the correctional facility subtype for 99% of the blocks.

To make the file more widely known, we:

  • Sent out a press release to our mailing list the same day the Bureau made the data available. We received immediate confirmation and thanks from a number of redistricting experts, particularly those who work with county and municipal governments.
  • Sent out approximately 3,000 individual letters to most of the county commissioners and city councilors in the nation who have both a district form of government and a large prison in their jurisdiction. Letters sent out before the file was available described how and when to get the Advanced Group Quarters Summary File, and most letters sent out after the file was available included the specific block level data relevant to their community. We also offered additional technical support on request. Despite our letter not asking for a response, we received a number of thank you calls. We also saw considerable traffic on our website related to the file.

To support users of the data file, we also:

  • Had numerous conversations about using and interpreting the data, including to assist New York State with implementing their law against prison gerrymandering. As the Bureau expected, Maryland officials also found the data useful when they redistricted in accordance with their own law.

By planning ahead to make the the Advance Group Quarters Summary File available, the Census Bureau took a big step forward towards ending prison gerrymandering at a time when it was too late to tabulate incarcerated people at their home addresses in the 2010 Census. Now, though, with the 2020 Census seven years away, the Census Bureau can plan ahead and develop the methodology needed to ensure that the next census counts incarcerated people in the right spot: at home.
