Hello, 

I am conducting an analysis of internet availability in the state of Alabama. I am comparing this against income and race at the census tract level. I need to review the data for patterns among those things. Do you have any suggestions for the tool within ArcMap to use for this? 

Additionally, the data I have for internet availability is at the census block level. I need this to match the census tract level of the other data. I have tried utilizing the zonal statistics tool for this but I am not having great results. The data I have on the tract levels is in a polygon format and when I change this to raster the output is very over generalized and not exactly specific to the tracts, only to large cell blocks. 

Thank you so much for any help!

you will need to aggregate the block level data to the census tract level.  You should usually be able to find a "key" to do this with the census data. Examine your block level data and see if there is a census tract column indicating which one it belongs to.  You can then dissolve the block level data and aggregate the values
