These data are a roll up of 2013 monthly CalWIN extracts to come up with unduplicated counts of kids and adults, by program, aided at any time in 2013. One caveat is that SSA doesn’t have all the Medi-Cal enrolled in the local county data system (CalWIN). While it’s the vast majority, there are missing people, for example kids who get onto Medi-Cal via SSI, Foster Youth placed in Alameda but on MC from another county, and those who applied in CalHEERs but they haven’t made it into CalWIN yet. This file has the field definitions.
