Creating Custom Demographic Datasets with API Tools

.. develop national scale spreadsheet files with virtually no learning time .. easy-to-use API operations to create national scope demographic-economic datasets based on American Community Survey 2016 1-year estimates .. custom subject matter selections. See more detail in related web sections ACS2016 and ACS2016_API.

Benefits and utility … how to acquire a spreadsheet showing the population of all cities with population estimates based on the ACS 2016 1-year data? … or, housing units, median household income, median housing value, etc.? Variations of this need frequently arise — what is the list of largest California counties sorted on total population: What are the 25 metros having the highest median household income? Which 10 congressional districts have the highest poverty incidence? Which urban areas have the highest educational attainment?

Use simple API calls described below to get answers to these types of questions — and more.  Create files that can be used for recurring applications. An example …

Urban Areas with 2016 Population 65,000+ Population
… results from using the API downloaded data … the following graphic shows urban areas with 65,000 or more 2016 population; zoom-in to Texas. The full national scope GIS project is available as described below; examine U.S. or any region. The file used to develop this view was created using the results of the API call reviewed below (requires integration of those data into the urban areas shapefile).

Navigating the U.S. Federal Statistical System

.. an overview of the Federal statistical system and how to access data  .. the U.S. Federal Statistical System offers a vast array of diverse data resources that are useful in wide-ranging planning and analytical applications. Many of these data resources, such as census block level demographics from the decennial census, are unique in scope and content; in many cases there are no alternative data resources.

But there are issues/challenges for the data user to navigate the Federal Statistical System. Examples … the Bureau of Labor Statistics releases total employment data by county quarterly and monthly through multiple programs. The data values differ, for methodological reasons, but the net result can be confusion. The Census Bureau releases total employment data from many statistical programs by county both annually and more frequently. Where are these alternative total employment data and how can they be accessed? How do these various measures differ and which data are right for my situation? This section provides basic statistical program information. Subsequent updates will provide more detail.

This section provides an overview of the U.S. Federal Statistical System (FSS) and information that can help stakeholders navigate access to selected types of data produced by the FSS. While the FSS is focused on agencies that collect, develop and make available statistical data, there is a broader set of data and resources that relate to accessing and using these data. As technology and related data analytics resources have evolved, access to and use of these data is closely associated with the development of geographic data by Federal statistical and other agencies and Geographic Information Systems (GIS).

The FSS is a decentralized set of agencies that collect, develop and make available statistical and geographic data. The OMB Office of Statistical Programs and Standards (SPS) provides a FSS coordinative role. The SPS establishes statistical policies and standards, identifies priorities for improving programs, evaluates statistical agency budgets, reviews and approves Federal agency information collections involving statistical methods, and coordinates U.S. participation in international statistical activities.

While the FSS spans more than 100 agencies, the 13 “principal statistical agencies” have statistical work as their principal mission. Excluding funding for the decennial census ($919.3 million requested for the Decennial Census for FY 2016), approximately 38 percent ($2,486.9 million of the $6,486.6 million total proposed for FY 2016 President’s budget request) of overall funding for Federal statistical activities (of the Executive Branch) provides resources for these 13 agencies. The principal statistical agencies include:
Census Bureau (Commerce)
Bureau of Economic Analysis (Commerce)
Bureau of Justice Statistics (Justice)
Bureau of Labor Statistics (Labor)
Bureau of Transportation Statistics (Transportation)
Economic Research Service (Agriculture)
Energy Information Administration (Energy)
National Agricultural Statistics Service (Agriculture)
National Center for Education Statistics (Education)
National Center for Health Statistics (CDC/HHS)
National Center for Science and Engineering Statistics NSF/Independent
Office of Research, Evaluation, and Statistics — SSA/Independent
Statistics of Income (IRS)

The remaining 62 percent of the FY 2016 budget involves more than 100 programs that conduct statistical activities in conjunction with another program mission. These statistical programs are components within a Federal department or other agency. They include a broad set of centers, institutes, and organizations in addition to the 13 principal statistical agencies.

There are also Federal agencies whose statistical activities are not part of the Executive Branch. These agencies include the Congressional Budget Office, which develops and applies projection models for the budgetary impact of current and proposed Federal programs; the Federal Reserve Board, which compiles the widely used Flow of Funds report and other statistical series and periodically conducts the Survey of Consumer Finances; and the U.S. Government Accountability Office, which uses statistical data in evaluations of government programs.

Analyzing ACS 2014 1-Year Supplemental Data

.. examining 2014 characteristics of areas with population 20,000 and over  .. this section summarizes how to use the America Community Survey (ACS2014) “supplemental” data (ACS2014S) to access more current estimates than otherwise available. The America Community Survey “supplemental” data are just that, a supplemental set of ACS 2014 1-year estimates — for areas 20,000 population and over. See the related Web section providing more detail.

The importance of the ACS 2014S data are two fold.
1 – 2014 1-year estimates for a larger number of areas than available from the ACS 2014 1-year (ACS2014) estimates.
2 – more current (2014) data for those areas only available from the 5-year estimates (centric to 2012) that are between 20,000 and 65,000 population.

The ten cities/places with the highest 2014 median family income based on 1-year estimates were all under 65,000 population. These cities were not included in the ACS 2014 1-year standard estimates but were included in the ACS 2014 1-year supplemental estimates. See list below.

This section provides an overview of the ACS 2014 supplemental data and provides a summary of tools, interactive table and GIS project, to analyze characteristics of these areas. These data are used by ProximityOne to develop/update annual county demographic-economic projections. See schedule of related 2016 updates.

Scope of Expanded Geography Available
As shown in the table below, 2014 1-year “supplemental” estimates are available for more than twice as many counties from the ACS2014S compared to the ACS2014 “standard” 1-year estimates. However, there area a more limited set of subject matter data available from the ACS2014S data compared to both the ACS 2014 1-year and 5-year estimates.
