POPULATION
PYRAMIDS
US, Minnesota, Lake City
Created 2017; 2015 data
Overview
• A population pyramid can help us identify future needs
•
•
•
•
based on population density by age.
Assuming static in- and out-migration, we can use this
data to predict needs for city and other resident services,
Consider that in 5 years, the 0 – 5 year old age group will
be 5 – 10 years old and be in the school system
In 10 years, most of our 65 – 69 year old age group will
be retired and likely to need more medical services
Compare the shape of the Lake City population pyramid
to that of Minnesota and the US to see where our future
needs may align or be different from the rest of the state
and country
