Population Growth Calculation

The federal census bureau's estimate of state population (census estimate) for the previous calendar year, as of December in the current calendar year; and The census estimate for the current calendar year, as of December in the current calendar year.

This method for calculating population growth can lead to either double-counting or under-counting of population changes in census estimates. If the federal census bureau revises a census estimate upward for a given year, population growth will be understated and the fiscal year spending limit will be lower. The opposite is true if the federal census bureau revises a census estimate downward. In either case, under this method for calculating population growth, population growth would be measured inaccurately.

The act adjusts the method of calculating population growth. Under the act, population growth is calculated by determining the percentage change between:

The census estimate, as of December in the previous calendar year, for the previous calendar year; and The census estimate, as of December in the current calendar year, for the current calendar year.

This approach prevents double-counting or under-counting population changes as a result of revised census estimates and results in a more accurate measurement of population growth. (Note: This summary applies to this bill as enacted.)
