Term | Definition |
---|---|
Linear Method | Uses the rate of growth (or decline) in a population over a period of time to estimate the current or future population |
Exponential and Modified Exponential Method | Uses the rate of growth (or decline) in a population over a period of time to estimate the current or future population |
Step-Down (Ratio) Method | Uses the ratio of the population in a city and a county (or a larger geographical unit) at a known point in time Such as decennial census |
Symptomatic Method | Uses available data to estimate the current population Correlation between population and other events (e.g. tax returns, school enrollment, etc.) |
Distribution Housing Unit Method | Census bureau data for the number of housing units. which is then multiplied by the occupancy rate and persons per household |
Cohort Survival Method | Uses the current population plus natural increase and net migration to calculate a future population |
Trend Extrapolation | Takes the past and projects it into the future Methods: Linear Exponential Gompertz |
Gompertz | A family of curves, describing demographic growth, that increase exponentially at first before reaching a plateau. |
Allocation Methods | Ratio Method (Step-Down) Distributed Housing Unit Method |
