Appendix F: Community Impact Index

The operational changes discussed in this guide will not affect every community in the same way. This appendix provides a quick crosswalk identifying the parts of the 2030 Census design that deserve particular attention for several populations that have historically experienced undercounts, data-quality problems, access barriers, or other census-related risks.

The list is illustrative, not exhaustive. The communities identified here overlap substantially, and people may experience several of these risks at once. A disabled immigrant living in rural housing, for example, may be affected by language access, accessibility, address quality, administrative-record coverage, and field capacity simultaneously.

See the visual version of the Community Impact Index below.

The sections below explain what each community’s row means in practice.

Children

The most important risks for young children involve household rosters, administrative records, residence rules, and coverage measurement.

Young children have historically been undercounted at especially high rates and may be missing from administrative sources even when their parents appear. They may also be left off questionnaires in complex or multigenerational households or associated with the wrong address when parents live apart.

Priority issues include:

  • whether administrative records identify young children reliably;

  • whether PCF household rosters include children who are not connected to major benefit or tax systems;

  • how shared-custody and other complex residence situations are resolved;

  • whether field strategies provide additional effort when children may be missing; and

  • whether Coverage Estimation and Demographic Analysis can independently identify remaining undercounts.

The central question is whether 2030 innovations help Census find children who traditional methods have missed rather than allowing incomplete records to confirm the same omissions.

Immigrants

Immigrant communities sit at the intersection of language access, trust, administrative-data quality, confidentiality, self-response, and field enumeration.

Some immigrants will be well represented in federal administrative systems; others may appear incompletely, at outdated addresses, or not at all. Recent migration can also make Census Day residence harder to establish.

The larger challenge may be willingness to participate. Immigration enforcement policies or fears about government data use can affect whether residents respond directly, answer a fieldworker, or trust a community organization encouraging participation.

Priority issues include:

  • preservation of multilingual response and outreach;

  • direct-response opportunities before administrative enumeration;

  • quality of administrative records for recent immigrants;

  • confidentiality and safeguards against enforcement use;

  • access to trusted community messengers; and

  • measurement of differential nonresponse and undercount.

For these communities, operational quality and trust cannot be separated.

LGBTQ People

The most important issues for LGBTQ communities are questionnaire content, household relationships, administrative-data quality, privacy, and the usefulness of final data products.

Administrative sources may contain outdated or inconsistent information about names, sex, household relationships, or family structure. Automated household reconstruction may also perform poorly for relationships that are less common in historical data.

Questionnaire and data product decisions determine whether LGBTQ people and families can be represented accurately at all.

Priority issues include:

  • preservation of accurate relationship and household information;

  • treatment of conflicting administrative and self-reported information;

  • whether direct response receives priority over older records;

  • confidentiality and restrictions on linked person-level data;

  • availability of relevant characteristics in public products; and

  • disclosure avoidance effects on small populations.

The basic principle should be that modernization does not substitute administrative assumptions for information people provide about themselves and their households.

People With Disabilities

People with disabilities are particularly affected by response-mode accessibility, communications, field procedures, telephone assistance, partnerships, and quality measurement.

An internet questionnaire may technically meet accessibility standards while still being difficult for some respondents to use independently. Paper, telephone, field, and assisted-response options therefore remain important.

Priority issues include:

  • end-to-end accessibility testing across response modes;

  • preservation of telephone and paper alternatives;

  • accessible partner and fraud-prevention materials;

  • training for field staff;

  • procedures for obtaining accommodations without creating additional barriers; and

  • whether quality measures can identify disability-related response disparities.

Accessibility should be built into the operational design before systems are finalized rather than addressed primarily through accommodations after the fact.

Incarcerated People

For incarcerated people, the central issues are Group Quarters Enumeration, residence rules, facility records, direct response, data quality, and redistricting.

Census generally relies heavily on correctional institutions to provide information about the people in their custody. That can reduce direct participation and make the quality of facility records especially important for race, ethnicity, age, and other characteristics.

Priority issues include:

  • opportunities for accurate self-report;

  • quality of facility-provided information;

  • confidentiality and protection from retaliation or inappropriate access;

  • application of residence rules;

  • disclosure avoidance for correctional populations; and

  • the downstream use of prison populations in redistricting.

Because incarcerated people have limited ability to correct census information themselves, Census should apply particularly strong quality controls to institutional data.

People Experiencing Homelessness

People experiencing homelessness may be affected by almost every stage of the census, but the most important issues are address coverage, specialized field enumeration, administrative records, residence rules, partnerships, and coverage measurement.

A census increasingly organized around addresses and administrative records can work poorly for people whose living situations are unstable or not tied to conventional housing.

Priority issues include:

  • identifying shelters and outdoor locations;

  • retaining effective targeted outdoor enumeration;

  • protecting confidential facilities;

  • accounting for people who move among shelters, temporary housing, outdoor locations, and doubled-up situations;

  • avoiding excessive reliance on administrative addresses that may be outdated;

  • working with trusted service organizations without limiting enumeration to people connected to services; and

  • independently measuring coverage after the census.

The operation must be capable of counting people who are absent from the very systems Census increasingly uses to make enumeration more efficient.

Tribal Communities

Tribal communities are particularly affected by addressing, geography, administrative records, language, field operations, disclosure avoidance, partnerships, and redistricting data.

National averages can obscure serious problems in individual tribal areas. Address conventions, rural and remote geography, administrative-data coverage, local languages, housing patterns, and governmental relationships vary substantially among tribes.

Priority issues include:

  • direct government-to-government engagement;

  • field verification of difficult addresses;

  • tribal input into geography and address programs;

  • administrative-record quality;

  • locally appropriate language and communications;

  • adequate local field staffing;

  • separate evaluation of tribal coverage; and

  • preservation of useful data for tribal and small-area geographies.

Tribal governments should be involved directly in the design and evaluation of operations affecting their communities rather than treated solely as one category within a national partnership program.

Rural Residents

Rural residents are particularly affected by address quality, paper and telephone response, broadband access, field capacity, enterprise centralization, administrative records, and small-area data products.

Rural communities are highly diverse, but many have fewer standard street addresses, longer travel distances for enumerators, weaker broadband, smaller local governments, and fewer community organizations available to support outreach.

Priority issues include:

  • Locate Address Test results and targeted field verification;

  • preservation of paper and non-internet response modes;

  • local recruiting and field supervision;

  • administrative-record accuracy in remote areas;

  • the effect of fewer physical Census offices;

  • geographic aggregation and suppression; and

  • preservation of usable data for small counties, towns, and rural communities.

Efficiency measures that appear modest nationally can have large effects in places where distances are greater and populations are smaller.

Using the Index

The matrix should be used in both directions – by organizations to help identify priority issues and by advocates looking to fill out their roster of collaborators.

Organizations representing a particular community can use it to identify operational areas that may deserve attention even when they do not appear to be traditional constituency issues. For example, an immigrant-rights organization may need to monitor matching algorithms and Coverage Estimation, not only language access.

Likewise, advocates working on a particular census operation should use the matrix to identify the communities that need to be involved. A discussion of administrative enumeration should not occur only among statisticians. A disclosure avoidance discussion should not occur only among privacy experts. A fieldwork redesign should not be evaluated without organizations that understand the populations most affected by reduced contact.

The index is therefore intended as a starting point for questions, not a prediction that every listed risk will occur.

The practical standard is: whenever Census changes an operation, ask which communities are most likely to experience the change differently, and make sure those communities are part of the research, testing, and decision-making before the design is fixed.
