Low & Moderate Income Census Tracts; 2017 Update

..  data and tools to analyze characteristics and patterns of census tract geography with a focus on low and moderate income.   See related Web page for more detail.

Of the total 75,883 census tracts for which low and moderate income data were tabulated in the HMDA 2017 data, 6,023 (8.7%) were low income, 16,873 (24.5%) were moderate income, 32,509 (47.1%) were middle income and 19,159 (27.8%) were upper income. See more about these classifications. Find out about your tracts/neighborhoods of interest and how they compare to others using data and tools provided in this section.

Analysis of the low, moderate, middle, and upper income of the population and households by small area geography is important to housing market stakeholders, lenders, investors, cities/neighborhoods and others. Low and moderate income data by block group and census tract are used for compliance, eligibility determination and program performance in many Federal programs and agencies.

• Use the interactive table below to view, query, compare, sort census tracts.
• Use tract estimates & projections to examine changing characteristics.

Low & Moderate Income by Census Tract
The following view shows census tracts designated as low and moderate income (orange fill pattern) in the the Houston, TX MSA (bold brown boundary) area. These are tracts having income level with codes 1 and 2 in the interactive table. A wide range of market insights can be created zoom-in views for counties, cities and neighborhoods and linking these with other data. Make variations of this view using ProximityOne data and tools described in this section.

– View developed using CV XE GIS and related GIS project.

Data Analytics & API Applications

Possibly the most well known APIs (Application Programming Interface) are the Google APIs. Among these, the Google Maps API, or its use, might be the most familiar. See about integrating political/statistical geography and Google Maps API. This section reviews different types of APIs.

Data Analytics and APIs
API technology/tools play an important role in accessing and integrating geographic, demographic and economic data. APIs offer two types of benefits. For Web-based applications, APIs provide the ability for on-the-fly access to selected demographic-economic buried in otherwise large datasets that typically otherwise involve downloading and preprocessing. A second important benefit/use is to extract data from those same datasets, reconfigure the structure of the data retrieved by API and create a new dataset structure that lends itself to analytical applications.

ProximityOne Data Analytics sessions review purpose, scope, strengths, advantages & limitations of APIs described in this section. Topics included in the related Web section include:
Federal Geographic-Demographic-Economic Data Access Using APIs
REST APIs
Federal Communications Commission
Bureau of the Census … much more than Census
Bureau of Economic Analysis
Bureau of Labor Statistics
Data Access & Analytics Applications
There are hundreds more APIs available from Federal agencies and wide-ranging sources.

Using APis and GIS: Visualizing Patterns; Geospatial Analysis
The following graphic has been developed first using API tools to create the underlying datasets. While the source data used in this application could have been downloaded and processed in legacy manner, the API tools provide on-the-fly development of the data in a structure required by the GIS software. These data are then integrated into shapefiles for use with the GIS software. Once the datasets are developed, they can be used in a myriad of application, GIS and otherwise.
