  1. aGender was a dummy variable coded 100 for males and 0 for females and with 0 as a reference category
  2. bSurvey year was a dummy variable with 1993 as a reference category
  3. cEthnicity/race was a dummy variable coded 100 for ethnic Han and 0 for other minorities and with 0 as a reference category
  4. dMarital status was a dummy variable coded 100 for Married and 0 for others and with 0 as a reference category
  5. eCommunity urbanicity was measured at the community level on a 12-component continuous scale ranging from 0 to 120 with higher values corresponding to higher levels of urbanicity
  6. fPer capita net annual household income was calculated at the household level for each survey year and inflated to 2011
