This is my first time using the IHIS data. I attempted to create an extract of most of the injury/poisoning variables for the years 2010-2014 and I get an extract that, when loaded in Stata, has all the standard identifier, weight, etc. variables (rectype, year, serial, strata, psu, nhishid, …, pernum). But all variables of interest (e.g. rectypei, yeari, seriali, nhisiid, irinjnum, irpoisyn, …, irbody1, irbody2, irpoison, etc. etc.) are missing/empty. Are there just several years with no observations? These variables I chose all had ticks in the ‘select data’ area.
Sorry if this is a dumb question. I am very confused by what I’m getting here.
Thanks very much.
