Report: Wis. will gain 800K-plus people by 2040

Elderly population will double in Wisconsin

A new report from Governor Scott Walker’s administration says Wisconsin will gain more than 800,000 people over the next 30 years and get dramatically grayer.

The report projects the population will grow to 6.5 million by 2040, up 14 percent from 2010. Increased migration and more births than deaths will drive the growth. The increase will slow around 2030, however, as baby boomer deaths rise and migration slows.

The elderly population, defined as 65 or over, will double, from 770,000 in 2010 to 1.54 million in 2040.

The very elderly population, defined as 85 or older, will grow to 287,000 by 2040 — an increase of 142 percent from 2010. The state’s population of centenarians is expected to grow from 1,200 in 2010 to 3,900 in 2040.
