The pandemic impacts on America’s cities in different ways .. some experiencing little change, others with massive change. When, where and how will these disparate patterns change in cities and communities of interest? How might this change impact you and your community? A comprehensive plan needs to be developed and set in motion to achieve best outcomes. This section provides access to tools and data that stakeholders can use to examine America’s cities demographic-economic characteristics and trends. Examine cities of interest. Use ProximityOne data, tools, methods and advisory services to achieve improved results.

Of the nation’s 327.2 million people, an estimated 206.0 million (62.9%) live within an incorporated place. Of approximately 19,500 incorporated places, about 76 percent had fewer than 5,000 people and nearly 50 percent had fewer than 1,000 people. Examine characteristics of individual city population trends and compare cities in states, regions and peer groups using the interactive table below.

Financing America’s Schools

.. as we look to restarting America’s economy, the nation’s public school systems face many questions and logistical issues.  Among these issues are a wide range of financial challenges.  Financing America’s public K-12 schools is supported by a mix of Federal, state and local funding.  In FY 2017, 13,311 regular public school districts reported total revenues of $679,925 billion derived from $51,212 billion federal (7.5%), $317,434 billion state (46.7%) and $311,278 billion local (45.8%) sources. These data are based on the school district finances (F-33) program data released by the Census Bureau in May 2019. States and individual school districts vary widely on the make-up/distribution of these federal, state and local sources.  See more about this topic and related K-12 schools topics in the ProximityOne K-12 schools main Web section.

Use tools and data reviewed here to examine K-12 school district finances — sources and uses of funds for FY 2017. View, sort, query, compare school district sources and uses of funds using the interactive table below in this section. Create/view profiles for district(s) of interest.

Data and resources reviewed here update in early May 2020 with new FY 2018 sources and uses of funds data and related school/school district financial data. We examine the implications of COVID-19 for school systems as we look to Restarting the EconomyJoin the User Group to receive updates.

Relating ZIP Codes and Census Tracts

.. what census tracts intersect with a ZIP code of interest? There are many reasons for the underlying the need to convert/equivalence ZIP codes to/from census tracts. Some organizations have to provide census tract codes for addresses/ZIP codes of clients to be in compliance with a law or regulation. Some organizations have addresses/ZIP codes of clients/locations for which they would like to determine the corresponding census tract codes to analyze census tract demographics. This post reviews tools and options for these operations. See related Web section to access interactive table and learn more about mapping and geospatially relating these two geographies.

Phoenix/Scottsdale, AZ ZIP Code-Census Tract Relationship
The following graphic illustrates the relationship between ZIP code area 85258 (orange fill pattern) with census tracts (green boundaries and geocode labels).
(StCtyTract=04013216813).
.. view created with ProximityOne CV XE GIS software and related GIS project.

Create your own maps of areas relating ZIP codes and census tract, in context of other geography. Use the CV XE GIS with shapefiles.

Using the Interactive Table
Use the ZIP code to census tract interactive table (opens new page) to answer questions such as:
• Which census tracts intersect with a ZIP code of interest?
• Which ZIP code(s) intersect with census tract(s) of interest?
• What is the Census 2010 population for a census tract and ZIP code combination?

The interactive equivalence/look-up table shows a row for each unique combination of a Census 2010 ZIP code area and Census 2010 census tract. The start-up view is sorted on the State-County-Tract column (StCtyTract). View ZIP codes in one state using the State selection button. To locate a ZIP code of interest, either use the Find ZIP query or sort on the ZIP code column and then scroll down the table until the ZIP of interest is located.

Example. Click Find ZIP button using the interactive table (opens new page) to view only the tracts intersecting with ZIP code 85258 (as shown in map view above). The Location 1 marker (see pointer in map) is located in the area intersecting ZIP code 85258 and census tract 2168.13. The refreshed table view is shown by the graphic below. There are nine tracts intersecting with this ZIP code; see the tract codes in the table.

Try this for a ZIP of interest:
• View the interactive table (opens new page).
• Click the Showall button below table.
• Key in your 5-digit ZIP code in edit box where 85258 now shows.
• Click Find ZIP button.
• Table refreshes showing only tracts intersecting with this ZIP code.

Scope of Tracts and ZIPs in Table
There are 150,806 rows in the table, each showing a unique combination of a census tract (73,057 Census 2010 tracts) and ZIP code area (33,120 Census 2010 ZCTAs). Each row represents an intersection of the specified census tract and ZIP code area and corresponds to a geographic area of one census block or more. The total population and housing units values have been derived by summing component census block values. The sum of the population column is 308,745,538, the United States Census 2010 total population.

The 2018 American Community Survey (ACS 2018 main) is a nationwide survey designed to provide annually updated demographic-economic data for national and sub-national geography. ACS provides a wide range of important data about people and housing for every community across the nation. The results are used by everyone from planners to retailers to homebuilders and issue stakeholders like you. ACS is a primary source of local data for most of the 40 topics it covers, such as income, education, occupation, language and housing.

Examining HMDA/CRA Census Tract Demographics

.. the ability to effectively analyze low, moderate, middle, and upper income 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. See the main Web page for more detail.

This section reviews the scope and use of the FFIEC 2019 HMDA/CRA census tract data (released September 2019). Use the interactive table to view, rank, compare selected items from these updated data for any/all tracts. Use GIS tools with these data to map and geospatially analyze these data as illustrated and further described as illustrated here.

Low & Moderate Income Population by Census Tract
Low, moderate, middle, upper income classification by census tract is based on the median family income of a specific census tract relative to the metropolitan statistical area (MSA) or non-MSA area in which the tract is located. The FFIEC data include a “low and moderate income indicator”:
1 – Low — MFI is less than 50% of the MSA/parent area MFI
2 – Moderate — MFI is from 50% to 80% of the MSA/parent area MFI
3 – Middle — MFI is from 80% to 120% of the MSA/parent area MFI
4 – Upper — MFI is 120% or more of the MSA/parent area MFI
0 – NA — MFI is 0 or not available
where MFI is the Median Family Income

Low and moderate income designation is closely associated with implementation of the Home Mortgage Disclosure Act (HMDA) and the Community Reinvestment Act (CRA) and is a widely used in many other applications as a measure of economic prosperity.

Using the Interactive Table
Use the interactive table to examine individual tracts or sets of tracts as to their low and moderate income status and related demographics. The following view illustrates use of the table. Clicking buttons below table, this sequence of steps was used to obtain this view:
– click ShowAll
– click “Find CBSA; Low & Mod Tracts”
  >this selects tract in CBSA 26420 (Houston) that are low or mod
– click “Status Cols”
The table refreshes to show 470 tracts that are low/mod in this metro.
Finally, click the column header “Tract MFI %Region” to sort in descending order.

Census Tract Demographic-Economic Characteristics & Trends

..  Census tract demographics are used in wide-ranging public and private sector applications to examine patterns and characteristics of sub-county areas. Tract level data from Census 2000Census 2010 and the American Community Survey (ACS) can be used to analyze trade/market areas, neighborhoods and other small area study areas. But what about more current data and trends since 2010? What about business establishment data and other subject matter not included in either the census or ACS data?

There are no current demographic-economic census tract data available from the Census Bureau or other Federal statistical programs. Annually released ACS 5-year estimates are available by census tract but are for 5-year periods and dated. The most recent census tract level ACS data are based on the ACS 2017 5-year estimates (ACS 1317). Those data are not for the year 2017 but estimates for ACS survey respondents for the 5 year period 2013-2017; centric to mid-2015.

The Value of Demographic Insights

Click graphic for larger view; expand browser window for best quality view. What are the insights from these data, this view? How are the insights developed? Their application and use creates the value. .

– U.S. by state interactive table.
– U.S. by metro interactive table.
– U.S. by county interactive table.
– U.S. by city interactive table.
– U.S. by census tract interactive table.

An example of the “tip of the iceberg,” the above model-based demographic data have been developed for use in developing the more detailed American Community Survey annual demographic data — annual updates on demographics down to the block group level of geography. ~217,000 areas covering the U.S. wall-to-wall.

Valuation of Demographic Insights
Having the required demographic data is needed before value can be assigned to their use. It’s really not possible to value demographic data or insights on a financial basis alone. But here are some considerations. One way to assign a value to demographic data is on the cost basis. The above data have been developed by the Census Bureau. But they are not free to develop — the costs for the Federal programs to produce them and the cost for others providing access to the data and using them.

These demographic data enable an unestimable number of studies that result in an unestimable set of decisions in the private and public sector. Many evolve into useful insights, but certainly not all.

Census 2020 is will cost in excess of $16 billion. That’s just to get the data out there. The value of these demographic data have to be in the many trillions or much more. Plus, these demographics enable things that can be done that cannot be done with any other set of demographic data. This “uniqueness thread” runs through many demographic data programs. What is the value of being able to apportion Congress, state legislatures and thousands of other governmental bodies?

How to assign value to one decision based substantially on geodemographics?

What about the byproducts? Census 2020 relies heavily on the Census produced (with the indispensable involvement of regional governments) TIGER/Line geographic database. In essence, we have a demographic data program producing a geographic database. It can be argued that the public use TIGER database is the most valuable past of the decennial census. TIGER provides the digital map database undergirding all widely used mapservers such as Google maps and Bing. It provides the unique and near comprehensive set of standardized geographic data going down to the intersection-to-intersection street segment. It enables a near infinite set of Geographic Information System (GIS) applications.

The above addresses mainly matters of demographic data developed on a national scale. All businesses deal in their own demographics daily. This set of demographic data minimally includes staff and related consultants, etc. plus prospects and clients/customers. Many businesses do not take advantage of the potential benefits of having these data. They can often do more to use their own data, and data of competitors and about the market, to develop improved plans to meet their goals.

Census Block, Block Group & Census Tract GeoDemographics

Census tracts, block groups and blocks are the important small area statistical geographic areas for which data from Census 2010 are tabulated. Data for census tracts and block groups are also tabulated annually from the American Community Survey. For example. in December 2018, we will have new “richer demographics” annual estimates centric to each year 2008 through 2015 for Census 2010 tracts and block groups … data such as educational attainment, language spoken, housing and household characteristics,  income characteristics and employment and other demographic-economic attributes.

Census 2010 and Census 2020
These geographies have generally stable geographic areas and codes from one decennial census (e.g., Census 2010) to the next (e.g., Census 2020). Many of these areas will change in terms of code and area for Census 2020, though the geographic changes will typically be small or not at all.

Census 2020 block, block group and tract codes and geometry will be available in late 2020. Initial block level demographics will be available in March 2021.

Census 2010 & Current GeoDemographics
These areas cover the U.S. from wall-to-wall and generally non-changing in terms of boundary and geographic code (geocode) until Census 2020. This section provides a summary of new Web pages with more detail about each of these geographies:
census tracts and tract codes .. 73,056 areas
census block groups and block group codes .. 217,740 areas
census blocks and block codes .. 11,078,297 areas

Each of these pages provides an interactive table to view tallies of Census 2010 for each of these small area geographies.

Combining Address Data with Small Area Geography
The address of the Office of the California Secretary of State, located at 1500 11th St, Sacramento, CA 95814, was geocoded using the APIGeocoder and converted into a shapefile for Geographic Information System applications.  The location is shown as a red marker in the map views shown below, illustrating each type of small area geography: tracts. block groups and blocks.

Census Tracts
Tracts are labeled with green tract codes. Address 1500 11th St, Sacramento, CA 95814 is shown by red marker.  The address is in tract 06067001101.

Is the tract code 11.01 or 001101?
Both. Census tracts within a county are identified by a 4-digit basic code between 0001 and 9999, and may have a 2-digit suffix ranging from .01 to .98; for example, 6059.02. The decimal point separating the 4-digit basic tract code from the 2-digit suffix is shown in Census Bureau printed reports and maps. For geo-referencing, the decimal point is implied and does not appear; the 6-character tract code with lead zeroes is used — a character string with no blanks and all numbers.

Accessing and Using these Geographies & Related Demographics
There are several ways these geographies can be used.
• The geocodes are the “handles” to access demographic-economic statistical data.
• The geographies may be visually, geospatially, related as shapefiles.
.. the Census Bureau makes these shapefiles available for use in user appications.
.. the shapefiles typically do not include demographic-economic data.
