We use the SECC 2011 data from 14 states to estimate the percentage of households that have a female Head of Household (HoH), the variation in percentage of female HoH by last name (see here for how we deduce last names; we limit inference of female HoH by last name to last names shared by at least 1000 households) and by SC/ST/Other. We also estimate the average age of female and male HoH.
About 11.7% of the households have a female HoH. Expectedly, the age of female HoH (~ 54.1 years) is generally higher than a male HoH (~ 47.3 years). The percentage of female HoH doesn't vary much by SC/ST/Other but varies widely across last names, with the 10th percentile being 2% and the 90th percentile being 17.6%.
