Definitions

The US Census reports extensively on the topics of age and sex, often reporting other topics broken down by age and sex cohorts. This page reports on age and sex alone; charts presenting other topics by age and sex can be found on their topic-specific pages.

  • Children: less than 18 years old
  • College: from 18 to 21 years old
  • 20s: from 22 to 29 years old, to not overlap the college category
  • Younger Adult: from 22 to 39 years old
  • Older Adult: from 40 to 64 years old
  • Senior: more than 64 years old

Unlike the other geographical entities detailed on this site, neighborhoods are not recognized by the U.S. Census Bureau. To overcome this we have computed reasonable estimates of the same statistics that are presented for other the entity types. Each statistic is computed as the weighted sum or average of the census tracts or block groups that overlap the neighborhood. A weighted sum is used for counts of people or households, and a weighted average is used for statistics that are themselves some form of average, such as median household income. Census block groups are preferred when the statistic in question is available on the block group level. The weight for a given tract (or block group) is computed as the population of the census tabulation blocks that occupy the intersection between the tract and the neighborhood as a fraction of the total population of the neighborhood.
