I was able to map values by county in California, but I am trying to map by census tract. I downloaded the census tract file from census bureau and it shows 8,041 values. For the values, I pulled in the census block. How do I get the census block to match up to the cb_2017_06_tract_500k shapefile? The values in this attribute table are StateF, CountyFP, TractCE, AFFGEOID, GEOID, NAME, LSAD, ALAND, and AWATER.
Census Blocks roll up to Tracts via the TRACTCE column, which is present in both tables. Here are census tracts (black outline and labeled with TRACTCE) and the underlying Blocks (symbolized by their corresponding TRACTCE which relates to the Tract they fall within):
If you have data for Census Blocks and want to map the data at the Tract level, you'll have to summarize and group that column by TRACTCE, then you can join it back to the Census Tracts by the TRACTCE.
