and a long life involving nonrecurring expenditures
• What is a Capital Improvement Program?
– A guide to the provision of capital improvements by
balancing revenues, expenditures, as well as

Certificates of Obligation

(PERT): Project management technique that
defines shared activities and creates a
sequence of events.

critical path of activities to complete a
project.

Organizational Center
• Staff Functions – Support line positions
– Budgeting, Human Resources
• Line Functions – Provide direct service
– Water, Parks
Work Areas
• Function – transportation, historic
preservation
• Process – zoning review, demographic
analysis
• Time – current v. long range
• Area - neighborhoods
Centralization
• Centralized - functional
• Decentralized – typically by area
Comprehensive Planning
• The official statement of a legislative body that
sets forth its major policies concerning
desirable future physical development
• Should be adopted by the governing body
• Key Elements

Analysis of information (quantitative and
qualitative)
• Demographics
• Fiscal impact analysis
Statistics
Key Topics
•
•

•
Data Types/Measurement
Descriptive Statistics
Normal Distribution
Sampling Distribution
Estimation
Types of Statistics
• Descriptive – describes data
• Inferential – tells about population
– Sample statistic to estimate population
parameter
Types of Data
• Nominal: no order: social security number
• Ordinal: order, but no magnitude: letter
grade
• Interval: order, magnitude, but no fixed
interval: example temperature
• Ratio: order, magnitude, and interval (used
for measures of central tendency): distance
Measures of Central Tendency
• Mean (average)
• Median (middle number), best for skewed
data
• Mode (most frequent number)

Sources of Data
Methods of Data Analysis
Population
• Current Estimates
– Most recent US Census
– Migration and Natural Increase
• Birth and Death Rates (aggregate)
• Net Migration – school enrollment
– Step Down Method
• Using data for state/county/MSA
– Other: Telephone hookups, electric meters
• Population Projections
Population Projections
• Growth Curves
– Take Current Population and Historical
Population to identify a pattern of growth, which
is used to estimate future population.

Population Projections
• Step-down Methods (state, county, MSA)
– Use ratio of population of community to a larger area
• Cohort Survival
– Birth Rate/Death Rate
– Migration Rates
Population Pyramid
Source: Vicki Male
Birth Rates
• Need a birth rate of 2.1 to maintain the
population size
• Birth rates are generally going down
– Europe birth rate of 1.5 (European Union)
– United States rate of 2.0 – 2.1 (US Census)
Data Sources
• US Bureau of the Census
(http://www.census.gov)
• FedStats (http://www.fedstats.gov)
• National Center for Health Statistics
(http://www.cdc.gov/nchs/)
• State-level Department of Health for
information on birth and death rates
Employment Data
• US Bureau of the Census – 5 year economic
census (http://www.census.gov)
• County Business Patterns
(http://www.census.gov)
• Census Transportation Planning Package
(http://www.fhwa.dot.gov/ctpp/)
Economic Base Analysis
• Economic Base Analysis tries to determine the
multiplier effect
– Location Quotient (concentration of a given industry
in a given place and compares it to the nation)
Location
Quotient =
Regional Employment in
Industry I in Year T
Total Regional
Employment
in Year T
/
National Employment
in
Industry I in Year T
Total National
Employment
in Year T
Economic Base Model
• If Location Quotient is >1 exporting
employment
• If Location Quotient is <1 importing
employment
• Basic Activities can be exported, while nonBasic Activities cannot be exported
Multiplier Effect
• Total Employment/Basic Employment
• 20,000/10,000 = 2.0
• Every basic employee generates 2.0
employees. That person plus 1.0 additional
employees.
Shift-Share Analysis
• Analyzes change in employment in a given area
and given industry
• Look at two periods
• Between 1990 and 2000 the helium industry
increased employment by 3 percent in the Amarillo,
Texas Metropolitan Area. The MSA’s employment
increased by 10 percent.
• Between 1990 and 2000 the helium industry growth
was 5 percent nationally and overall employment
grew 10 percent.
