Age (2020 American Community Survey Estimates)

The City of Keizer has seen a drop, as a percentage of the total population residents nineteen and younger.  This may be the result of a combination of limited supply of housing available and a rise in the average price of available housing preventing households with young children from finding a “starter” type home.

The drop in young children is in contrast to the increase as a percentage of the population of those 55 to 74 years of age.

Keizer appears to be trending towards an upper middle-class community as the percentage of households earning more than $75,000 has increased.  The largest increase is in the $100,000 to $149,999 category.
