An unintended consequence of getting the new birth data with addresses is that the older data (which used tracts to create summary files) are no longer on the summary files.
One option is to create a second summary file just for old data and merge it on as necessary. The other option is to update the new Births_sum_all_address.sas program so that it uses the new system for newer data and the old system for older data to create a single summary file.
