Census Tract Demographic-Economic Estimates & Projections
-- examine small area, subcounty change and how it may impact you
November 2019. Census tract demographics are used in wide-ranging public and private sector applications to examine patterns and characteristics of sub-county areas. Tract level data from Census 2000, Census 2010 and the American Community Survey (ACS) can be used to analyze trade/market areas, neighborhoods and other small area study areas. But what about more current data and trends since 2010? What about business establishment data and other subject matter not included in either the census or ACS data?
There are no current demographic-economic census tract data available from the Census Bureau or other Federal statistical programs. Annually released ACS 5-year estimates are available by census tract but are for 5-year periods and out-of-date. The most recent census tract level ACS data are based on the ACS 2017 5-year estimates (ACS 1317). Those data are not for the year 2017 but estimates for ACS survey respondents for the 5 year period 2013-2017; centric to mid-2015.
ProximityOne Census Tract Estimates & Projections
ProximityOne provides annual U.S. national scope census tract demographic-economic-business estimates and projections for the period 2010 through 2024 (2019 vintage). This section provides information about these estimates and projections. These census tract level data are part of the ProximityOne Situation & Outlook database and information system.
Annual census tract level estimates and projections are available for the period 2010 through 2024. "5-year projections" are updated and extended annually. For the 2019 vintage estimates and projections, the estimates are for 2010 through 2019. The projections are for the period 2020 through 2024. The 2020 vintage data (released in mid-2020) extend the projections by one year to 2025.
Tract estimates and projections subject matter are summarized below. These data are also available summarized to the county, metro/CBSA, state and U.S. national level.

There are 317 fields in each census tract record.
Each census tract record (73,056 records) is iterated for each year, 2010 through 2024.
Accessing & Using the Estimates and Projections
There are several ways the census tract demographic-economic estimates and projections may be accessed and used.
Data File License -- county, metro, state, U.S.
Integrated with CV XE GIS/Modeler Software -- geospatially analysis; data linkage
.. ready-to-use GIS projects with integrated tract-county-metro-state- national estimates & projections
SiteReport -- create custom geographic area reports/analyses
HTML/XLS Reports -- structured reports for one or several tracts
Tract estimates and projections are developed using holistic, metro/county-centric, integrated demographic-economic-business models. We use a range of sub-county data to document change at the tract and sub-tract levels. These data include USPS delivery data; motor vehicle registrations; building permits, completions and occupancy data; housing sales; business establishment and attributes data and special developments that have or may have an impact on sub-county demographic-economic change.
As noted at the top of this section Census Bureau American Community Survey (ACS) estimates released annually for census tracts are 5-year estimates. This means the estimates are for a 5-year period, not estimates for that year. year to year 5-year ACS estimates are not intended to be comparable.
1. ProximityOne tract estimates and projections are annual data. They are estimates for that Calendar year or as of July 1 in that year. ProximityOne annual estimates and projections are intended for year to year comparisons.
2. We develop annual time series historical data used with models to develop current estimates and projections. The process/models use a population components of change and cohort-survival equations:
P[i,a,t]=P[i,a,t-1] + B[i,a,t:t-1] - D[i,a,t:t-1] + M[i,a,t:t-1]
where P is population, B births, D deaths, M net migration, i tract, a age/race-origin cohort, t year
3. The number of housing units, households and vacant units are developed using a composite of data including our new construction, mail deliveries, and related data:
H[i,a,t]=H[i,a,t-1] + HN[i,a,t:t-1] - HR[i,a,t:t-1]
where H is housing units, HN new units, HR units removed, i tract, a type of unit, t year
a, units in structure: 1-unit, 2-units, 3-4 units, 5+ units
H[i,a,t] and P[i,a,t] are controlled to the county level.
4. Other items are developed using multi-equation time series models. A generic model specification is used and adjusted for different regions where, for example, different assumptions are used as well as cause and effect relationships. Where applicable, these items are also controlled to the county level estimates and projections.

ProximityOne develops geographic-demographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses. Wide-ranging organizations use our tools (software, data, methodologies) to analyze their own data integrated with other data. Follow ProximityOne on Twitter at www.twitter.com/proximityone.
