Population Group Characteristics & Trends

.. tools and methods to access and use population group data .. demographic-economic attributes of population groups. Population group (age by race/origin by gender) data are important to understand the population diversity and race/origin-gender characteristics for an area such as county or metro. Annual population group data are important to understand how the population group mix is changing. Population group projections help us understand how the mix might change in the future and impact the workforce, public sector resource allocation and planning in general.

A "population group" can be defined many ways. In this section, population group refers to population that are a subset of the total population based on race/origin, gender and/or age. Characteristics of population groups are tabulated by many Federal statistical agencies (FSS) in many statistical programs. This section is focused mainly on data tabulated for population groups from Census 2010, American Community Survey (ACS) and model-based estimates and projections.

ACS Population Group Tables
ACS table numbers and descriptions are shown in the table shells Excel file. The table shells file shows what data have been tabulated as summary statistics that are available in the form of files or accessible via the Web. Use the table shells file to determine items tabulated/available.

Scroll down in the table shells file to see that table "B01001" (population by age and gender) is iterated as "B01001A" through "B01001I". The appended/final character identifies the population group for which the table B01001 cells are tabulated. Data for nine "population groups" are available. Population group codes are shown below.

A White alone
B Black or African American Alone
C American Indian and Alaska Native Alone
D Asian Alone
E Native Hawaiian and Other Pacific Islander Alone
F Some Other Race Alone
G Two or More Races
H White Alone, Not Hispanic or Latino
I Hispanic or Latino

Manipulating the table shells file, the population group subject matter tables are presented in the table shown below. In this table, only the "A White alone" population group is listed. The table sets exist for each population group A through I.

The "B" tables, determined by first character in table code in the first column, are available "down to" to the block group and higher geographic levels. For example, to access table B01001A table/cell B01001A_001E for Dallas County, TX, use the API instruction:,B01001_001E&for=block+group:*&in=state:48+county:113

In the resulting CSV-like file that is displayed, the second row shows the value of "1385" for item B01001A_001E for state "48", county "113", tract "000100", and block group "1", See more about using the API in the API Tools section and the ZIP Code Data Analytics section.

Population Group Profiles & Data -- goto top
The low-level geography for these data is county. Estimates and projections are updated annually for the U.S. by county.

These profiles/data provide a detailed race/origin by gender profile for a selected area. The profile is available for any county, metro or state and the U.S. Illustrative profiles show data for 2010, 2015 and change 2010-2015. Profiles are available for any combination of years 2010 through 2030.

The profiles are based on estimates developed by the Census Bureau and estimates/projections developed by ProximityOne. ProximityOne develops U.S. national scope demographic estimates and projections to 2060 that include population by population group. These data are developed as part of the Situation & Outlook program. Annual population estimates and projections for the period 2010 through 2060 by county by single year of age crossed by race/origin crossed by gender. See more information about these data, methodology, access and use.

Contact ProximityOne to acquire population group profiles/data for areas of interest. Use the app to create profiles for any area, any selection of time periods. Create a profile for a single year of age, a custom defined age group or total across all ages as shown in the examples. Inquire about accessing the interactive table to view, rank, compare population groups across areas. Key in a message in text section "population group data/profiles".
