Urban SDK provides data to streamline projects revolving around spatial analysis, transportation, people, and planning with live and historical data.

The Population datasets are reported once per year by the United States Census. The data reflect the number of persons residing in the boundary defined by the US Census. The dataset is available to download through the Urban SDK Data Hub for the years 2015 - 2020. The data has been aggregated to the census tract.

Census Population Definition

The US Census collects reliable population information across the United States. This information is useful to federal, state, and local governments, private businesses, universities, international organizations, and researchers. Population information is used by these organizations to allocate, or advocate for funding, inform policy, and aid in city planning. The public has an interest in population information to gain an understanding of their community.

Annual census population data has been sourced from surveys such as the American Community Survey (ACS) and the Current Population Survey (CPS), and the periodic Survey of Income and Program Participation (SIPP).

Detailed Calculations

geo_id

The “GEO.ID” field contains 14-digit codes that identify the summary level of data, the geographic component of the data, and FIPS codes that uniquely identify the data. For example, the 14-digit “GEO.ID” for Harris County, TX is “0500000US48201” where “050” represents the summary level of the data, “0000” represents the 2-digit geographic variant, and the 2-digit geographic component, “US” represents the United States, “48” represents the state of Texas and “201” represents Harris County.
