Notes: Summary statistics for household heads in two different samples. Column 1 corresponds to statistics for Jakarta computed from the 2008 Susenas households survey. The subsequent columns report data for 160 household heads in the field survey. The statistic for whether the household head was born in Jakarta was obtained from the 2010 population census (this variable was not available in the 2008 Susenas).
