(51 cards)
LQ
Ratio of industry’s share of local employment/share of the nation
LQ<1 = importing LQ>1 = exporting
Formula: (local employment in I)(total local employment)/(reference area employment in industry I)(total reference area employment)
FAR
Total floor area / total lot area
Oregon model
1st place to pioneer use of community based visioning
Interval data
Ordered relationship where the difference between scales has a meaningful interpretation EX temperature
Qualitative
Nominal, sometimes ordinal
Quantitative
Interval / ratio
Symptomatic method estimation
Used available data indirectly related to population size such as housing stats
Economic base analysis
Looks at basic / no basic economic activities. Basic = activities that can be exported, non basic = those local.
Stratified sampling
Mini reproduction of pop, divided into characteristics of importance
Cluster sampling
Specific target group is sampled
Systematic sampling
Every xth person is selected
Non probability sampling
No precisé connection between sample and population. Ex: convenience sample, snowball sample, volunteer sample
Projections
Calculated for future population levels (trend lines, scatter plot, regression)
Forecasts
Cohort survival, step down
Bias
Different between expected value of an estimator and real value.
Sampling error
Natural consequence because sample is small
Fiscal impact analysis is different from economic analysis
Economic focuses on cash flow to private sector
Transect zoning
T1-T6 (natural-rural, suburban, general urban, urban center, urban core)
Performance zoning
Performance standards regulate development by setting desired goals. Doesn’t restrict specific uses, just that uses must meet specific set of standards
Progressive tax
Tax rate increases as income increases
Proportional tax
Tax rate is the same regardless of income
Regressive tax
Tax rate decreases as income rises
ACS vs. Census
Acs: conducted every month, every year. Asks topics not on census (employment, education etc)
Census: every 10 years, shorter questions and provides official list of population for congressional representation
Census trends 2020 census
South shifting population. More than half of nation’s population growth in last decade (54%) occurred in southern states
