*Note: Each year of available data shown above is a 5-year estimate, or an average of data collected over a five year period. 5-year estimates are used to increase the reliability of the data at small geographies like neighborhoods and census tracts. The years shown on the NDSC map represent the final year of the five year average (e.g. “2010” represents 2006-2010 data, “2011” represents 2007-2011 data, and so on). For the most impactful comparison of data over time, the ACS recommends comparing non-overlapping years (e.g. 2010-14 with 2015-19).

Why are these variables important to measure?

Average Household Size

A household is defined in the American Community Survey as all the people who occupy a housing unit, which can be a house, an apartment, a mobile home, or any other space that is occupied as separate living quarters. Since households can be occupied by single or multiple families, groups of unrelated people, or single persons, it is important to specify the type of living arrangement that characterizes them. 

Household size is important to measure to aid in understanding the living conditions and quality of life of the inhabitants of a neighborhood. This, in turn, can help identify problems such as overcrowding, rent burden, and shortages in housing supply; informing the design of interventions to address them.

Children in Single-Parent Households

Households where children are living with only one parent can be comprised of solely the parent and children, or include other unrelated inhabitants as well. A household is defined in the American Community Survey as all the people who occupy a housing unit, which can be a house, an apartment, a mobile home, or any other space that is occupied as separate living quarters. Since households can be occupied by single or multiple families, groups of unrelated people, or single persons, it is important to specify the type of living arrangement that characterizes them. 

Understanding the percentage of children living in single parent households helps assess the living conditions of children in a neighborhood, as well as their residential arrangements. This is is essential for the design and provision of services, government programs, and provide for children’s educational and health needs.
