Internet Access

November 2024

This project gives data on household Internet access in Alabama by county. The data are from US Census Bureau for the year 2022.

Definitions

NCHS Scheme

Of particular importance for healthcare is the urban-rural classification scheme developed by the National Center for Health Statistics (NCHS), part of the Centers for Disease Control and Prevention (CDC). This scheme is based on Core-Based Statistical Areas (CBSAs), and so applies to counties, but is enhanced and adapted specifically for health statistics. It has four urban levels and two rural levels (ordered from most urban to most rural):

  1. Large Central Metro
  2. Large Fringe Metro
  3. Medium Metro
  4. Small Metro
  5. Micropolitan
  6. Noncore

The first five are associated with CBSAs. The last level, Noncore is not associated with a CBSA, hence the name. So a Noncore county could be considered completely rural.

Blackbelt Counties

In Alabama, the term blackbelt refers to counties in the central part of the state that traditionally have been poor, rural, and marginalized (and hence vulnerable in terms of healthcare services). There is no universally accepted definition for the blackbelt counties of Alabama, but for purposes of healthcare, the following list is appropriate, and is the one used in this project:

FIPS

Federal Information Processing Standards (FIPS) are publicly announced standards developed by the National Institute of Standards and Technology for use in computer systems by non-military American government agencies and government contractors. FIPS 6-4 is a code for US counties and equivalents.

User Interface

Our data are displayed in the form of interactive maps and interactive tables. The maps generally have point or area layers that can be added or removed with the layer control on the map. The user can zoom in and out of a map and move about in the usual way. Zooming in reveals additional features such as small towns and then streets and roads. A click on the home button returns the map to its origional location and scale. The zoom-to-area button allows the user to zoom to a selected rectangular area of the map. Clicking on an object in a layer shows summary data for that object.

The interactive tables can be sorted by any field, by clicking on the header for that field. The buttons at the top allow the table data to be copied to the clipboard, in tab-separated text format, printed, or downloaded in various formats (tab-separated text, Excel, or PDF). With the search bar, the table can be filtered according to a text string.

In the interactive tables you can click on a row to select an object (community, county, PCSA) and see the object highlighted in the map. You can select as many rows as you wish. Click on a selected row again to de-select and remove the highlighting in the map.

Limitations

The information and data presented in this project are provided as a service to the educational and healthcare communities. Although care was taken in gathering the data at the time of posting, no warranties are expressed or implied as to the correctness or usefulness of the material. Moreover, the project should be viewed as a snapshot in time. Inevitably, the further from the time of posting the less accurate the data will be.
