block group lat-longs

 

Dear TMIP,

 

I’m looking for a table of lat-long for centroids of US block groups.

 

(I tried to create one with ESRI but I don't yet have write access.)

 

Can you point me to a downloadable table on the web?

 

(I googled it and found only the one from SafeGraph but it’s in geojson format which I can’t open and the converter on-line is limited to 1GB.)

 

Thanks.

 

Rob

Hi Rob,

You want the centers of population, found here:
https://www.census.gov/geographies/reference-files/time-series/geo/cente...
.

All the best,
Alex

Hi Rob,

In case you want to the geometric centroid, I have attached a TXT file that
contains a few lines of codes that you can run in R/R Studio to get a CSV
file that has three columns (GEOID, lon, lat). I used US counties as an
example in the code but you can easily change them to Block Groups.

[BTW, thanks Alex! I did not know that the Center of Population reference
files exists!]
