Critical Data Sources to Estimate Impact
2006 Demographic Multipliers Series
Based on records collected in the 1990s
State level ratios by housing type for newly built units
Cannot reflect recent changes
Not geographically specific
Current Public Use Microdata Sample (PUMS) Records
Based on annually updated survey
Reporting unit at 100,000 person unit (PUMA)
Variety of samples
Expanded list of ratios
Robust, more geographically specific, and cover
multiple types of impacts
Estimation Biases Using Old Multipliers
Average household size is declining or has remained
unchanged in 35 states between 2000-2010
Tend to overestimate impacts in suburban areas
Tend to underestimate impacts in established urban
centers and corridors
Findings in the Capital Region
Number of School-Age Children (SAC) increased in
all housing types in Maryland between 2000 and
2014
The 2014 SAC for 2-bedroom multifamily units varies
from 0.09 to 0.6 among the 19 PUMAs in the National
Capital Area
The SAC for 3-bedroom single-family units ranges
from 0.2 to 0.7 within the region.
School impact for single family units is higher in the
suburban area except in the southeast of Prince
George’s County
Ratios for Silver Spring area are lower than Maryland
SAC in multifamily units is above the average in the
southeast of Prince George’s County
Fiscal Impact Analysis
The framework was developed by Robert Burchell
and David Listokin in The Fiscal Impact Handbook.
Lincoln Institute attempted to rethink the framework
around 2007
Defined geography and direct impacts
Fiscal Impact Analysis Methods
There are 6 main approaches to conducting an FIA
The Average Cost approach is the simpler, more
commonly used method
The Marginal Cost approach relies on an analysis of
the supply and demand relationship for public
services. It views growth in a non-linear manner
The two approaches may result in dramatically
different estimates of development impact
A Mixed Average Cost/Case Study approach
combines the simplicity and ease-of-use of the
Average Cost approach. It acknowledges that
straight Average Cost approach is not ideal, but
includes aspects of the Marginal Cost approach
Fiscal Impact Analysis is entirely dependent on the
assumptions and data used. PUMS data can
provide better estimates of the key variables
underlying the impacts
Pennytown Case
Worked closely with the client and school district to
understand the community
Conducted a 10-year trend analysis of enrollment,
expenses by service and interviewed administrators
to understand service capacity
Used multiple methods and tested the multipliers
over ten years, and adjusted for the nature of the
occupants

Fiscal Impact Analysis
“[a] projection of the direct, current, public
costs, and revenues associated with
residential or nonresidential growth to the
local jurisdiction(s) in which this growth is
taking place.”
Page 1,
Burchell, Robert W. and David
Listokin, 1978. The Fiscal
Impact Handbook : Estimating
Local Costs and Revenues of
Land Development.
The Fiscal Impact Handbook, 1978

Definitions-978-1-4128-5504-4.html
30. NCAC-APA, June 2016
“Is growth good or bad for my
for community?”
• It depends…
• Development generates a host of new costs for
a municipality.
• But is will also generate new revenue.
• It is important that municipalities determine if
the new revenues offset the associated costs.
• FIA can help elected officials make fiscally
sound land use decisions.
31. NCAC-APA, June 2016
The Uses of FIA
• Planning Applications of FIA include:
– Land Use Policies
– Rezonings
– Annexations
– Redevelopment
• Budget and Finance Applications
– Capital Improvement Programming
– Revenue Forecasting
– Fiscal Planning
– Level of Service Changes
32. NCAC-APA, June 2016
Methods of Fiscal Impact
Analysis
• There are number of standard approaches to
choose from.
• The two most common include:
– The Average Cost Approach
– The Marginal Cost Approach
• The distinction between the two is fundamental
to FIA.
• They may result in dramatically different
estimates of the fiscal impacts.
33. NCAC-APA, June 2016
The Hybrid Approach
• Combines the Average Cost Approach with
a Case Study analysis.
• The Average Cost Approach is used to
calculate per-capita costs and revenues.
• The Case Studies are used to identify areas
of capacity constraints.
– This helps bring in the benefits of the Marginal
Approach.
34. NCAC-APA, June 2016
Data Needs
• At a minimum a good FIA requires:
– Description of the development
– Local Revenue and Expenditure Data
– Local Property Value Data and Tax rates
– Number of existing Residents and Workers
35. NCAC-APA, June 2016
FIA Steps
• Step 1: Estimate the number of
residents and/or employees
– Total Population
– School Children
• Based on the type of housing units
– PUMS data provides the most up-to-date
information
36. NCAC-APA, June 2016
FIA Steps
• Step 2: Estimate the costs associated
with the development.
– Not all spending categories will be
impacted.
• Step 3: Allocate Costs between
residential and non-residential uses
– The method depends on the cost
categories.
37. NCAC-APA, June 2016
FIA Steps
• Step 4: Derive per-capita and per-
employee expenditure estimates
• Step 5: Calculate total costs
– Operating Costs vs. Capital Costs
– Use case studies and interviews to
understand potential capital costs
– Assess need for new capacity
38. NCAC-APA, June 2016
FIA Steps
• Step 7: Estimate the revenue
associated with the project.
– Property vs. other revenue
• Step 8: Allocate other revenue to land
uses
– Estimate per-capita and per-employee
revenues
39. NCAC-APA, June 2016
FIA Steps
• Step 9: Calculate Revenue
– Property taxes
– Other revenue
– One-time revenue
• Step 10: Calculate the net-fiscal
impacts
– Revenue - Costs
40. NCAC-APA, June 2016
Potential Issues
• Property Tax Abatements
– Could pose an issue for the period where
any taxes are abated.
• The outputs are only as good as the
inputs.
41. NCAC-APA, June 2016
Pennytown FIA Case Study
• Hybrid Methods
– Modified per capita method, Case Study, Proportional
Valuation, Average Parcel-Value Method
• Operating and Capital Expenditures
• Tracking Expenditures for 10 Years
• Examining Trends and Exploring Fiscal Stress
• Identifying Slack Capacity
• Marginal Cost Adjustment
• Adjusting for inflation
• Adjusting for the characteristics of occupants
http://bit.ly/CDA-PennytownFIA
42. NCAC-APA, June 2016
CONCLUSIONS
• Fiscal Impact Analysis remains one of the
important tools
• Better data (current and geographically
specific) must be used
• Hybrid method should be used
• Questions and Discussions

COMMUNITY
DATA ANALYTICS
Plan with Confidence
Community Data Analytics (CDA) is ESI’s latest suite of data products and
services. CDA provides up-to-date customized demographic analyses and
projections for communities. Supported by a team of experienced planners,
analysts, modelers, and econometricians, CDA works with clients to
analyze local demographic trends and provide demographic multipliers that
planning agencies, school districts, and fiscal specialists rely on for
population forecasts and to understand projects’ fiscal, demographic, and
traffic impact.
CDA uses the Planning Ratio Estimation Program (PREP) to collect and
filter the data your community needs. PREP starts with selecting and joining
housing and person records from the most current American Community
Survey PUMS dataset (2010-2014), to create samples based on pre-
established criteria such Newly Moved-in Household, 55+ Household,
Transit Commuter, and so on. These reports are grouped into 54 housing
configurations. A planning ratio is then computed as an average or median
number per occupied housing unit for each configuration. PREP identifies
the statistical relationship between an individual PUMA and its larger
geographies and uses this relationship to generate the best estimates when
the sample size is not sufficient at the PUMA level.
Ensuring a community’s future success and development takes careful and
accurate planning. Smart planning can only be effective when it’s based on
the most up-to-date and precise data. CDA was created to provide this
necessary and actionable recent data and insight into economic conditions
and trends in communities across the United States. Its goal is to facilitate
better understanding of the current characteristics of a community, support
decision-making, and allow you to plan with confidence.
Stop settling for outdated information and let CDA help build your
community’s future.
