-- tools & data to analyze neighborhood level age, gender, race/origin, more -- determining & examining HMDA Low & Moderate Income census tracts January 2019. Census tracts are important for many reasons. It is easy to misidentify or misunderstand patterns and characteristics within cities, counties and metros which can become blurred using these higher level, more aggregate geographies alone. Many cities and counties that might be experiencing demographic-economic decline will often have bright spots that are groups of a few or many census tracts. See about using these data and tools for HMDA low and moderate income applications below This section is focused on tools, resources and methods that you can use to access, integrate and analyze U.S. by census tract general demographics data. The U.S. national scope Census Tracts Demographic-Economic Dataset contains approximately 600 subject matter items tabulated for each census tract organized into four subject matter groups: • General Demographics (this section) • Social Characteristics • Economic Characteristics • Housing Characteristics Use the interactive table in this section to view, query, rank, compare general demographics for all tracts in the U.S. Data in this section are based on the American Community Survey (ACS) 2017 5-year estimates. Current Estimates & Projections ACS tract/small area estimates lag by four years or more between the current year and reference year. ACS does not produce current year annual estimates but estimates based on a 5-year period. The 2017 ACS estimates are centric to 2015. Use the ProximityOne annual tract estimates and projections 2010 through 2023 for current year (e.g., characteristics as of 2018) estimates and anticipated change 5 years ahead. Patterns of Median Age Census Tract The following graphic shows percent population age 65 and over (item D017 in the interactive table below) by census tract based on ACS 2017 5 year estimates. Zoom-in view focused on Texas showing Austin-Round Rock, Dallas-Fort Worth, Houston, San Antonio metros with bold red-brown metros.

This map illustrates the geographic level of detail available using census tract demographics and the relative ease to gain insights using geospatial data analytics tools.  - View developed using CV XE GIS and related GIS project. Use the interactive ranking table in this section to view, query, rank, compare general demographics of the population, households and families in these areas. The scroll box shown below lists each of the subject matter items available for each area via the ranking table. The number at the left of the subject matter item is also used as the short name for the subject matter item in the column header in the ranking table. General Demographics Items

Examining Low & Moderate Income Tracts .. goto top The following graphic is a zoom-in view of Los Angeles city. Based on HMDA criteria tracts that are low income are labeled with "1" and tracts that are moderate income are labeled with "2". 
The Site Analysis tool is started to selected/extract data for specific tracts for further analysis. tracts.

Click this link to open the file: tracts17_06037_site1.dbf (open with excel) Importance of Census Tracts for Data Analytics Census tracts are important for many reasons. • Covering the U.S. wall-to-wall, census tracts are the preferred "small area" geography for superior data analytics. • The Census Bureau now produces annual tract demographic-economic data from the American Community Survey; .. there is an evolving time-series at the tract level creating new analytical opportunities. • Originally developed to equivalence neighborhoods, many still do. • Defined by the Census Bureau in collaboration with local groups, .. tracts typically reflect boundaries meaningful for local area analysis. • Defined generally for use with each new decennial census, most tract boundaries are stable .. and non-changing for ten years and many much longer. • Designed to average 4,000 population, .. there are more than twice as many census tracts (73,056) than ZIP code areas (33,129). • Tract boundaries are well-defined; unlike ZIP code areas which are subject to multi-sourced geographic definitions. • Many data developers (e.g., epidemiologists) use census tract geography to tabulate their own small area data .. enabling more effective use of those data with Census Bureau census tract data. • A statistical geographic area (in contrast to politically defined areas), .. census tracts are coterminous with counties; .. data at the census tract level can be aggregated to the county level. • Small area estimates for tracts are typically more reliable than for block groups. .. census tracts are comprised on one or more coterminous block groups. .. on average, a census tract is comprised of three block groups. • Census tracts are used by many Federal, state and local governments for compliance and program management. The ACS provides "richer" demographic-economic characteristics for national scope census tracts. While Census 2010 provides data similar to those items in the General Demographics section, only ACS sourced data provide details on topics such as income and poverty, labor force and employment, housing value and costs, educational participation and attainment, language spoken at home, among many related items. The approximate 600 items accessible via the tract dataset are supplemented by a wide range of additional subject matter. ACS census tract data are updated annually in December of each year. Find Geocodes Based on Address go top Summary of steps to use the "Find tract code based on address..." tool located in the upper right of this page. • Enter an address in the three line form (no ZIP code). • Click Find button and the census tract and related geocodes are returned. • Copy the last 11 digits of the returned GEOID to clipboard (e.g., 06085508101). • Paste that value in the edit box to the right of the "Select Area" button below the interactive table. • Replace the first two characters (e.g., 06) with the uppercase USPS state abbreviation (e.g. CA). • Click the Select Area button; the table refreshes with the selected tract. .. optionally right click the row and copy tract attributes to clipboard. .. paste in application such as spreadsheet program. .. join us in a Data Analytics Lab session to review use of operations. • Table empty? Click the ShowAll button then click Select Area button again. Use the Location-Based Demographics tool to view a demographic profile for an address.
