Less technically complicated, good for smaller area projections. The farther out the projections, the more the margin of error.

Technically complicated, lots of data, good for large area projections like states or large metropolitan areas. Most common
Cohort=age group, Component=the three components of demography (fertility, mortality, migration)

Question 10

Extrapolation Methods

Answer 10

Good at the county level, bases growth on observed growth trends, watch out for mitigating factors.

Question 11

Symptomatic Methods

Answer 11

Regression analysis can be used for small areas.

Question 12

Housing Units Methods

Answer 12

Similar to extrapolation but good at a local level.
