What is the residential demand for home heating fuel by type in the Wheeling, WV MSA?
How is the demand distributed by type by census tract?
This section shows how to develop and view/use data from the 2017 American Community Summary data at the census tract level to get answers to these questions.
.. generalizable to any metro (or other summary level)
.. generalizable to any demographic topic
In the Wheeling metro overall, the number of housing units by type of heating fuel is shown via this link:
https://factfinder.census.gov/bkmk/table/1.0/en/ACS/17_5YR/B25117/310M300US48540
To map/geospatially analyze these data, proceed as follows ...
A summary of the steps:
1. access the required subject matter data.
1.1. determine the list of subject matter items
1.2. determine the list of census tract codes
1.3. use VDA Desktop GIS APIGateway with data from 1.1. and 1.2. to create the MSA by tract data file
1.4. optionally use the data from 1.3. with a program like Excel, stopping here.
Optionally proceed to create map to visually, geospatially, analyze the data.
2. use VDA Desktop GIS Database>dBMerge to merge the data in 1.3. into the exist tract shapefile.
3. Use the VDA Desktop GIS with associated GIS project to view/analyze the data.

1.2. determine the list of census tract codes
Create Geographies (tracts) file
Use c:\cvxe\1\api_geo_tracts73056.txt
Select tracts in three counties (determine county list from metro S&O report):
39013 Belmont County
54051 Marshall County
54069 Ohio County
save following tract codes to file c:\cvxe\1\api_geo_tracts_wheeling.txt

1.3. use VDA Desktop GIS APIGateway with data from 1.1. and 1.2. to create the MSA by tract data file
Start File>APIGateway:
Open the Geographic Areas file
Open the Subject Matter file
Select the Geography Level as Census Tract
Select the Datasets as ACS 2017/5yr
Empty the RecLimit edit box
Click the Run button; processing takes a few minutes.
The file c:\cvxe\1\apinewfile.dbf is generated.
The new file has a row for each tract and column for each subject matter item.
Close the form when processing complete.
The grid shows tracts as rows and subject matter items as columns.
Column headers show the item code/field name.
Extracted file may be viewed in VDA Desktop GIS Database>DBrowse (file appears similar in Excel):
2. use VDA Desktop GIS Database>dBMerge to merge the data in 1.3. into the exist tract shapefile.
Merge into shapefile dbf: CB_2017_US_TRACT_500K_ACS2017.dbf
(files cannot be in use)
or cb_2017_tracts_wheeling.dbf (three county variation):
geoid like '39013%' or geoid like '54069%' or geoid like '54051%'
DBMerge form closes when complete.
Open the GIS project with the shapefile that was updated.
Use Layer Editor to label tracts with item B25117_001 (total housing units)
See in view below ... pointer in tract labeled with 1720 housing units.
See ShapeViewer profile to right of map.
There are 1,127 occupied units (households).
Of the 1,197 owner occupied units, 535 are estimated to use utility gas for heating.
