People's Guide to Redistricting explains what redistricting is and why it matters to residents across U.S. government levels. It describes how district boundaries change every decade with Census Bureau counts, how equal representation connects to one-person-one-vote, and how timing varies by state and locality. The guide outlines available census data, common fairness goals, and the growing role of public input and citizen participation. It also discusses accessible tools such as online map-drawing software and focuses on local engagement rather than political objectives.

People's Guide to Redistricting Prepared by: Caliper Corporation 1172 Beacon Street, Suite 300 · Newton MA 02461 [www.caliper.com](www.caliper.com) People's Guide to Redistricting Introduction What is redistricting and why should you care about it? Every ten years, district boundaries at many levels of government are redrawn in conjunction with the release of the Census Bureau’s official head count of all individuals residing in the United States. While redistricting of congressional districts attracts prominent attention in the press, redistricting is also performed for the election of state legislators and for the elected officials of county, city, and other local boards. The districts that are drawn directly impact the representatives that are elected and the decisions they make on behalf of you and the other residents of your community. Many of these decisions on budgets, policies, and investments will determine how your tax dollars are spent and what benefits are derived therefrom. Shifting population totals lead to a requirement to redistrict – to redraw existing district boundaries – to ensure each resident has equal representation. Equal representation includes fair treatment in apportionment of public funds as well as a preservation of a one-person-one-vote relationship in elections. This is an approximate relationship in that only citizens have the right to vote and not all citizens choose to do so. The timing and frequency of redistricting will vary by state and locality as each has its own laws and regulations that apply to redistricting. However variable, redistricting will be widespread in the U. S. after the 2020 Census data are released in August 2021. The redistricting data are limited to counts of population, population by race, and voting age population. The data are reported at the census block level, which is the smallest geographic unit used for tabulation. From the census block level, totals for larger units such as precincts, census block groups, census tracts, minor civil divisions, and counties can be readily computed and are also published by the Census Bureau. When districting is done fairly, it helps ensure each vote is counted equally. Some common goals and requirements apply to redistricting at all levels. These principles are necessary to ensure fairness and compliance with prevailing laws. They, however, do not guarantee outcomes that will meet your objectives or anyone else’s. In contrast to past decades, most states are now planning to incorporate some form of public input or citizen participation in their redistricting processes. Those charged with local redistricting may also feel a commitment to provide public access. Public interest groups have historically played a role in redistricting or in challenging it and will be even more of a presence in the redistricting performed with the 2020 data. Because there will be widespread public access to redistricting in the coming months and years, you are likely to have the opportunity to contribute your thoughts as to the best district boundaries. You do not even need to be a citizen or a voter to participate. However, if you wish to make a meaningful contribution to state or local redistricting, you will need to be armed with the right knowledge to make suggestions that are lawful and realistic. In this guide, we will attempt to provide you with useful background information on redistricting and guidance on how you can be effective in contributing to the redistricting process in your locale. We will also provide examples that illustrate key points about redistricting principles and acceptable, fair districting solutions. Due to the large amount of data involved, computer software such as Maptitude for Redistricting is used by redistricters to draw boundaries that meet legal and other requirements. Maptitude for Redistricting is intended for professional use and has a great many features and metrics that are relevant for cr

FAQs

What is redistricting and how often does it happen?

Redistricting redraws existing district boundaries to ensure equal representation. It typically occurs every ten years in conjunction with the Census Bureau’s official headcount release.

What data does redistricting rely on and at what geographic level?

Redistricting data include counts of population, population by race, and voting age population. The data are reported at the census block level, and totals for larger units can be computed from those blocks.

How can residents participate in the redistricting process?

Many states are planning forms of public input or citizen participation, and governments or consultants may provide public access through online tools. Residents may contribute map ideas, comment on proposed plans, or critique existing ones depending on local options.
