Size and Growth
Missouri has slipped to the nation's seventeenth most populous state as a result of lower than average growth. Missouri's rank among the nation's most populous states has been on the decline since the turn of the century, when Missouri ranked the fifth most populous. Missouri's standing fell two positions during the decade of the 1990s dropping from the fifteenth spot in 1990 to seventeenth by 2000.
Methodology
A widely used demographic technique called the "cohort-component" method is used to project Missouri's population. The basic equation is "population at the beginning of the time period + births for the time period - deaths for the time period ± migration for the time period = projected population at the end of the time period."
