import delimited "ACD_SystemMembers_v2015.csv", encoding(UTF-8)

* Label variables:
label var statenum "ACD State Number"
label var stateab "ACD State Abbreviation"
label var statename "ACD State Name"
label var startyear "ACD Membership Start Year"
label var endyear "ACD Membership End Year"

* Quickly make an overall mat structure of country-years:
expand 2012-1946+1
sort statenum
egen year = seq(), from(1946) to(2012)

* Drop observations that are outside the member's start and end years:
drop if year < startyear
drop if year > endyear
