Examining Access to Healthcare Resources
  -- expanding insights through data analytics

July 2024 .. Healthcare resources, such as hospitals, clinics and physician offices, are not geographically equally accessible throughout the United States. These resources are located substantially more in urban areas and less in rural areas making it difficult to obtain full service healthcare in large swaths of the U.S. While there has been a proliferation in growth of health clinics, not hospitals, most do not provide many hospital services and overnight stay facilities.
  • In this section, availability of healthcare resources are examined for the Phoenix-Mesa-Chandler, AZ Metropolitan Statistical (MSA .. see about in interactive table).
  • Healthcare resources are examined at the neighborhood in context of the dependency ratio and urban/rural settings.
  • Use the VDAGIS tools to examine this phenomena for any area of interest throughout the U.S.
  • One purpose of this section and toolset is to support development and operation of congressional communities, superneighborhoods comprised of typically 15-18 contiguous census tracts.
  • See more about healthcare resources below as used in this section.
This section is also a guide used in the upcoming web session to be held on July 10, 2024 at 3:00 pm. There is no cost and no registration. We hope to see you there. See these connectivity details.

Next, we build a story using the following sequence of topics. Starting at the end of the story, the following graphic shows that healthcare resource exist mainly in the Phoenix MSA principal city area (red markers are hospitals in this zoom-in view of AZ CD 01 .. less to none in rural areas with high dependency ratio. Through congressional communities we seek a means to improve accessibility of healthcare resources .. read on.

Lay of the Land .. goto top
The Phoenix MSA is comprised of Maricopa and Pinal counties as shown in the following graphic.

Congressional Districts .. goto top
Congressional Districts intersecting with the Phoenix MSA are shown with bold brown boundaries and labeled in the following graphic. The next set of topics/views will focus on Congressional District AZ 01 and drill-down geography. See related congressional district interactive table.

Congressional District AZ CD 01 & Dependency Ratio by Tract .. goto top
The following graphic focuses on Congressional District AZ 01 and shows patterns of the dependency ratio by census tract. See that the dependency ratio is 115.15 (lower left profile panel) for an arbitrary tract near the pointer. In CD AZ 01 note the higher dependency ratios are in the north and west. These are predominately rural areas even though within the MSA.

About the Dependency Ratio In 2020, the dependency ratio for the total population in the U.S. was 63.6 .. children under age 18 and adults age 65 and older for every 100 working-age person ages 18 to 64.
  • The total dependency ratio provides a rough approximation of economic dependency in a population by dividing the dependent-age populations (children and adults age 65 and older), who are not generally expected to work) by the working-age population (ages 18 to 64).
  • In 2010, the dependency ratio for the nation as a whole was 49.0 .. the working-age population is not keeping pace with growth in older Americans.
  • In smaller cities, towns, townships and even counties, a higher and increasing dependency ratio can lead to a lower tax revenue leading to economic decline.
Congressional Communities in context of Congressional District AZ CD 01 .. goto top
The following graphic shows congressional communities (CCs) in context of Congressional District AZ 01.
  • CCs nest exactly within the corresponding congressional district.
  • Each CC includes 15-18 census tracts.
  • These approximate 7,500 areas have been developed by cc.org, are groups of census blocks and cover the U.S. wall-to-wall.
  • Typically, the availability of healthcare services vary widely by CC with the corresponding CD.
  • HRSA designations of "medically underserved area" or "health resource shortage area" may have little useful meaning to a CC or CD. Underserved or shortage areas should be assessed/addressed by CC and how CC underserved/shortages differ within a CD.

Congressional District AZ CD 01 & Urban/Rural Areas .. go to top
The following graphic focuses on Congressional District AZ 01 and patterns of the urban/rural areas .. light orange fill pattern. See that the In CD AZ 01 note the majority rural areas are in the north and west .. the same areas with higher dependency ratios.

Healthcare Resources .. goto top
In this illustrative section, CMS (Centers for Medicare & Medicaid Services) hospitals are used as a proxy for the broader set of healthcare resources which include "medical centers", clinics, physician offices and others. Hospitals registered with CMS are used in GIS applications.
  • There are at least three "Medical Centers" in CD AZ 01 that are not classified as "CMS hospitals" possibly meaning that the scope of services differ and many/all services may not be Medicare covered.
  • CMS hospitals might be specialized and thus not all healthcare services are available at any given CMS hospital.
  • Note that CMS defines rural hospitals as hospitals not in CBSAs/metropolitan statistical areas. This is not a recommended classification. Rural hospitals are those not located in urban areas. Urban areas are defined at the census block level. Most CBSAs include large swaths of rural areas, sometimes most of a county.
  • In general, a congressional community should assess healthcare resources available and how this differs from the broader area or congressional district.
The following graphic focuses on CMS hospitals in context of Congressional District AZ 01. Hospitals are shown by red markers. See that there are few to no hospitals in CD AZ 01 majority rural area.

Underserved & Shortage Areas .. goto top
.. under development .. here we will examine "medically underserved areas" and "healthcare shortage areas" using geography and attributes defined by HRSA. These data and shapefiles will be integrated with the tools and applications reviewed above.

These topics will be reviewed in the July 17, 2024 at 3:00 pm ET web session. There is no cost and no registration. We hope to see you there. See these connectivity details.

Examining Your Own Area .. goto top
In this section, you will learn to examine your own area. Use the types of geography, demographics and healthcare resources as used in the Phoenix application above for your area with the iVDA tool and VDAGIS "Base" project. See more about using iVDA in the VDAGIS Discovery section. VDA GIS resources have been developed, and are maintained/supported, by ProximityOne/Alexandria, VA USA and Tsukasa Consulting/Osaka, Japan.

In the iVDA frame below, the start-up view shows U.S. by county in the lower 48 states.

Suppose you want to examine healthcare resources (hospitals) in context of a county.
.. exact steps will be added to this section for the July 24 Web session.
.. the iVDA interactive mapping is active now .. start exploring.


Below is a static graphic example of using iVDA as described above.
