Population Estimates

Observations about current or past populations

Inexpensive updates to costly census counts

Methods are well‐established with known 

biases

Produced by the US Census Bureau, state and local 

agencies and private sector

Mortality

• Total deaths increasing due to aging population

• Mortality rates also increasing slightly 

• People are less likely to live long lives if they are poor, get little exercise or lack access to health care (Dwyer‐Lindgren, Bertozzi‐Villa, Stubbs, et al., 2017). 0

Assumptions

FertilityWill fertility continue to decline as it has been? Will it begin to rise, or will it remain stable?• Assumption: Fertility will remain at current rates

MortalityLife expectancy has increased for much of the past century but has been fairly stable in recent years.• Will we continue to live longer, or will poorer health behaviors lead to shorter lives? 

• Assumption: Mortality will remain at current rates

MigrationAssumption: Migration will continue at it’s net 2010‐2015 rate, thus capturing some in and some out migration.

Factors that could alter our trajectory

Increase in fertility among residents (not particularly 

realistic) 

Reduce out migration of young 

people

Attract young people to the state

Increased births due to more people of childbearing age
