Methods Flashcards
Evaluates the strengths and weaknesses of a specific region’s industries. It shows how well the region’s mix of industries are performing, and how well the region’s individual industries are performing. This analysis examines three components of regional employment growth (National growth, Industry Mix, and Competitiveness) between two periods of time. These three components are added to obtain the total change in employment of a specific industry.
Shift-share Analysis
Calculating population utilizes changes in obtainable data that are predictive of population changes as a whole (like building permits).
Symptomatic Method
Requires only housing or permit data to generate population estimates.
Distributed Housing Unit Method
Uses the difference between the population of a city and a county (or larger geographical unit) at a known point in time, such as the decennial census. This is used to project the current or future population.
Step-Down Ratio Method
Assumes portion of a sample’s type will remain the same over time.
Constant Share
Population projection method that extrapolates out based on past trends.
Linear Method
A population’s per capita (per individual) growth rate stays the same regardless of population size, making the population grow faster and faster as it gets larger.
Exponential Trend Extrapolation
As birth rates first increase and then slow as resource limits are reached.
Gompertz Trend Extrapolation
Uses current population + natural survival rates and net migration to project future population. Done for men and women.
Cohort Survival Method/Cohort Component Method
Takes various age groups and determines the estimate for each, then aggregates them together.
Composite Method
Divides the economy into two types of activities - base (those that can be exported) and non-basic (those that are to serve local demands. Exporting industries make up a region’s economic base.
Economic Base Theory
Shows what makes the region’s demographics unique in comparison to its state and/or the nation.
Location Quotient
of dependents aged 0-14 and over 65, compared with the total population aged 15-64. This demographic indicator gives insight into the # of people of non-working age, compared with the # of those of working age.
Dependency Rate
An economic factor that, when increased or changed, causes increases or changes in many other related economic variables.
Multiplier
During this process the range of the answers will decrease and the group will converge towards the “correct” answer.
Delphi Method
