Demographics in a Fire District

I agree with Doug's suggestion. The most precise way to do this would be using GIS and an overlay process to get a list of block groups that are within the boundary. There are GIS-compatible ACS files that you could then use to directly aggregate the data, or you could use GIS to create a list of block groups and then use data.census.gov to get the data.

However, if it's an area where you "just" have the street names, or if you don't have access to GIS tools, data.census.gov has a map selection tool that you could use to select all of the block groups within the area. (If the fire district doesn't quite align with block group boundaries you may need to make some assumptions about which overlapping ones are "in" or "out.")

There's a video tutorial for the map selection tool here: https://www.census.gov/data/academy/data-gems/2021/how-to-create-and-customize-a-map.html 

I wanted to let you know this has been helpful.  The key though actually came from being able to get some maps (courtesy of the MO University that has published the census tract and voting district with block #'s published online.  So, then, I went back to the data.census.gov and started pulling by block #'s.  It's quite tedious, but fortunately, this isn't a large area.  

Looks like I'm going to have to wait a few more weeks for the population data I would like to be published from the 2020 census.  Because I had to go back to 2010 census data to get a more detailed breakdown of the demographics.  If anyone is familiar enough w/the table names- would you have any suggestions on 1 or more table names for me?

Here is the kind of info that would be helpful  

Age ranges, not just below or above 18 (I believe the majority are near or past retirement age)

# of households

# of people per household or average is ok

Those are the main data points right now.  Thank  you.
