San Jose Demographics

The maps below give a feel for the age composition of the neighbourhoods that make up San Jose/Santa Clara County.  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 maps show a diagonal "corridor" of communities with a high percentage of young children, and a scatter of communities throughout the area with higher-than-average percentages of seniors.

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 Jose's population, by 10-year age group.  It shows that the area has many young working people, and a substantial percentage of young families and children.  Unlike San Francisco and Oakland, San Jose has a low percentage of people in the 60 and over age group, and a relatively high percentage of youth.
