American Community Survey
Sex estimates of the population are produced for places, zona urbanas and comunidades (place-equivalents for Puerto Rico), and minor civil divisions.The sex data collected on the forms are aggregated and provide the number of males and females in the population. These data are needed to interpret most social and economic characteristics used to plan and analyze programs and policies. Data about sex are critical because so many federal programs must differentiate between males and females.
