Importance of Census Tracts in Data Analytics

census tracts are important for many reasons. It is easy to misidentify or misunderstand patterns and characteristics within cities, counties and metros which become obfuscated using these higher level, more aggregate, geographies. 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.

This section reviews reasons for the importance of census tracts in data analyyics. See related Web sections 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
Social Characteristics
Economic Characteristics
Housing Characteristics

Importance of Census Tracts for Data Analytics
Census tracts are important for many reasons.  A partial list of reasons is provided below.
• 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.
• As 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 annually updated American Community Survey 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.

Mapping Statistical Data

.. GIS tools & data resources that you can use for statistical mapping & visual data analysis … Geographic Information Systems (GIS) provide flexible and powerful capabilities to combine maps with data. In our increasingly data rich environment, we often experience “drowning in data.” GIS tools can help harness disparate and voluminous data and assist with data linkage. This section provides links to other sections that provide information on no cost GIS software and “production” GIS projects and datasets that you can use.

GIS provides us with a way to improve collaboration; we can more easily comprehend and understand geographic relationships and patterns among “variables” and statistical data. As we reduce tabular data to visual representations, we are better able to communicate “what the data are telling us” among stakeholders and teams/committees. This second dimension, learning what the data are telling us, provides the power of creating insights for more effective decision-making.

Tools to Analyze the Local Area Employment Situation

.. December 2015; updated monthly … current, monthly data on the employment situation are essential to assess recent trends. The only historical source of these data for all metropolitan areas, counties and sub-county areas is the Bureau of Labor Statistics (about these data). The civilian labor force, employment, unemployment and unemployment rate are estimated monthly with only a two month lag between the reference date and the data access date (e.g., February 2016 data are available in April 2016). Historical monthly seasonally adjusted and non-adjusted time-series data are available. Use tools and resources provided/described in this section to access and analyze these Local Area Employment Situation (LAES) data. See related Web page with interactive ranking table.

Staying Ahead of the Data in 2016

.. effective use of information in anticipation of data releases .. The Federal statistical system uses scheduled release dates for wide-ranging statistical data. Anticipation of the implications of the data by users builds ahead of the actual release date. This section reviews major statistical release dates to help stakeholders “stay ahead of the data” and be prepared to make better use of the data. The continuously updated Statistical Release Dates for 2016 table can be a useful reference throughout the year.

Anticipation of Data Releases & Implications of the Data
Each month, stakeholders around the world watch for news about the Jobs Report, the Employment Situation, data developed by the Bureau of Labor Statistics. The Employment Situation is one of many key economic measures used to assess the strength and direction of the U.S. economy.

For the November 2015 Jobs Report, released December 4, 2015, the New York Times December 2nd story reflected “In the United States, most of the focus will be on the November jobs report, to be released Friday. Expectations are high.”

Many, convinced that the November data would be good news, took action in advance of the actual data release. The New York Times December 4th story “The U.S. economy created 211,000 jobs in November … The numbers did not disappoint … U.S. stocks jumped more than 2 percent … Stocks rallied in a sign investors are taking their cue from economic performance …” The Jobs Report is but one of many with monthly implications for planning and decision-making.

Staying Ahead of the Data
Planning in advance of the statistical release dates can often be as important as taking action based on what the numbers actually say. Upon the actual data release, a CEO might ask, “what do these data mean for our company and what might be the impact on us?” Good opportunities might have passed by that time. And, in the face of less positive news, the opportunity to take action might have passed.

Statistical Release Dates for 2016
See the full 2016 calendar. The graphic below shows a partial view of the 2016 data release dates. Items include selected key Federal and other demographic-economic statistics and related geographic data. The list builds on the list of “Principal Federal Economic Indicators” prepared by OMB. That list was developed in part to prevent early access to information that may affect financial and commodity markets and preserve the distinction between the policy-neutral release of data by statistical agencies and their interpretation by policy officials.


– click graphic to view full table.

Each row in the table shows dates for data releases. The table will update throughout 2016 and knits together with the ProximityOne calendar. The “Staying Ahead of the Data” section in the Metropolitan Area Situation & Outlook Reportsreviews upcoming data releases and anticipates the possible effects on that metropolitan area.

Comparing Census Tract Demographics Over Time

.. it’s about more than census tracts .. this section is about comparing American Community Survey ACS 5-year estimates: 2005-2009 with 2010-2014 … something new and powerful happening this week.

To make good business decisions we need hard data, recent data, trend data … to assess patterns and change and develop reliable, superior plans. Read about the past and then how things have changed for the better.

Imagine that it is 2005. Data from Census 2000 are now 5 years old. There will not be another update for richer demographics for all counties and cities in the foreseeable further. There will not be any update for small area geography such as census tracts or block groups until Census 2010. Businesses are forced to use out-of-date data to assess markets … where and how are opportunities changing? City and neighborhood planners can only make educated guesses to respond to growing needs of various population groups. Federal and state government programs that base funding allocations on demographics are challenged. Changes in the rental vacancy rates for most cities, counties and metros will remain unknown for the foreseeable future.

Fast forward to 2015 and present day reality. The situation is now radically different. First, we can now compare 5-year estimates from the 2009 American Community Survey ACS to those from the 2014 ACS 5 year estimates. Second, we will be able to do that again in 2016 — compare 5-year estimates from ACS 2010 to those from ACS 2015. Health planners can now assess the size and change in special needs population and how that matches up to resources that respond to those needs — rather than guessing. Schools and school districts can better understand how school age population trending and plan for enrollment change. Education agencies are better able to assess how changing demographics among school systems compare to one-another. Businesses can now determine the size of potential markets and how they are trending based on hard data. It is possible to compare changing patterns in rental vacancy rates and rental housing market conditions for all levels of geography down to block group.

The American Community Survey ACS provides a wide range of important statistics about people and housing for every community in the nation. These data are the only source of local estimates for most of the approximately 40 topics it covers for even the smallest communities. It produces statistics for ancestry, language, education, commuting, employment, mortgage status and rent, as well as income, poverty and health insurance. The ACS estimates are tabulated annually as 1-year estimates (e.g., the ACS 2014 1-year estimates) and 5-year estimates (e.g., the ACS 2014 5-year estimates. See a comparison below in this section about scope, advantages/disadvantages, and other usage attributes for the 1-year versus 5-year estimates.

See ACS 2014 5-year main page for additional data access & use details.

Data from the 5-year estimates are available for all geographies down to the block group level regardless of population size. Starting with the ACS 2014 5-year estimates, for the first time, users will be able to compare two non-overlapping five-year periods 2005-09 and 2010-14. Looking ahead, data from the 2006-10 and 2011-15 (available December 2016) will be comparable … and so on. Over several years, a time-series of 5-year estimates, non-overlapping five-year periods, will evolve.
