I am trying to analyze commute patterns using LODES data from the US Census. I downloaded a table that contained fields for home_census_block, work_census_block, and num_of_jobs. I joined that table to the census block geography using home_census_block as my join field. I then made a selection of census blocks that I wanted to analyze as the starting location for the commutes and made a new layer from that selection. I then created a relationship between the census block geography layer and the census block selection. The parameters for the Add Relate tool are:
Layer Name: census_block_geography
Input Relate Field: census_block_geography.GEOID10
Relate Table: census_block_selection
Output Relate Field: work_censusblockID
Cardinality: One to many
The Add Relate tool runs fine with no errors but I can't seem to get what I want. What I'm trying to see is what census blocks people are working in that live in the selected area. I have tried using the 'select related records' from the attribute table menu but nothing happens. I'm wondering if this is the right approach or is there something different I should be doing to get the desired results. Any guidance would be much appreciated.
Thanks,
Miguel
Unfortunately you cannot make symbols, definition queries, or queries based on a relate.
I think you can do it with some sort of relate table but I have worked on that yet.
Try a JOIN instead
