San Francisco Demographics

The maps below give a feel for the age composition of the neighbourhoods that make up San Francisco.  Each neighbourhood in the maps is coloured, with the colour representing the percent of the neighbourhood that falls in a given age group.

For example, the first map uses a light colour to show neighbourhoods where children less than 10 years of age make up a small proportion of the population, an intermediate colour for average neighbourhoods, and a dark red for neighbourhoods where children make up a high proportion of the neighbourhood population.

The demographics, or age composition, of a neighbourhood are an important indicator of what the neighbourhood is like.  For example, neighbourhoods with high proportions of young people have different needs and priorities (schools, playgrounds, summer jobs) than neighbourhoods with few youth.

The bar chart below reflects the overall age structure of San Francisco's population, by 10-year age group.  It shows that the most prominent age group in the city of San Francisco is young, working people.  Unlike most communities in the Bay Area, young children and teenagers comprise a relatively small fraction of the city's total population.
