Overview
In order to craft effective economic development
strategies, it is essential to understand the current state of the
local economy, including its relative strengths and weaknesses.
To learn more about your local economy, you are encouraged to conduct
a detailed study of its current and historical performance.
These tools are designed to help you address
a number of important questions.
- What are the current employment conditions
in your community?
- What parts of the local economy have been
growing? Which industries have been declining?
- How does the local economy compare to other
nearby economies? The state?
- What are the factors leading to local employment
growth?
- How do we identify new opportunities?
We offer these tools to help you get started
in examining important economic trends in your community. The methods
are flexible and can be used on a variety of economic indicators,
including employment and unemployment, income, poverty rates and
housing. The tools can use secondary data, readily available from
sources such as the Census Bureau, the Bureau of Economic Analysis,
and the Bureau of Labor Statistics. The analysis should help a variety
of local efforts, including industry development, grant writing
and visioning.
A few things to keep in mind when carrying
out the analysis
In practice, there are a number of indicators
that illuminate our understanding of the local economy, ranging
from simple descriptive statistics to in-depth surveys and analysis.
Regardless of the methods and measures chosen, there are important
guidelines that can help you make the most of your efforts. We urge
you to keep the following points in mind when using the tools developed
below.
1. There is no "single number" that
represents the local economy. When thoroughly assessing the local
economy, one needs to use several measures, as reliance on a single
measure provides only limited insight. For example, a high job growth
rate may show the community is generating new employment opportunities;
but there should be interest in the wages provided by new jobs as
well, in order to get a better understanding of the local labor
market's "true performance."
2. It is important to make comparisons among
communities. No community exists in isolation. In order to better
understand local economic performance, you should compare your community
to "similar" communities, the state and the nation.
3. It is important to examine changes over
time. While a "snapshot" analysis provides a good indication
of where the community is today, it is important to know long-term
trends in the community. With respect to employment, industries
that have traditionally been important may now be declining. Trend
analysis can be particularly informative as it often provides good
predictions about the near future.
4. A "reality check" is essential.
While using the methods here to analyze "hard data" is
a starting point, it is also important to tap the insights of local
citizens and policy makers. If the analysis and the data are at
odds, a more in depth examination may be necessary.
5. The analyst, not the data, should tell
the story. Always remember, economic data is boring, and no reader
wants to pour over reams of tables and charts. But the information
can be extremely helpful if it is used to complement a coherent,
consistent and truthful story about the economy. The information
is most useful when summarized with themes, interpretations and
conclusions.
Getting Started
Of course, the first step is to define the
"local" economy. While in reality the mobility of people
and money means any economy is not really place specific, it is
necessary to define some region as the local economy. For practical
reasons (i.e., data availability) "The Economy" is often
defined according to political jurisdictions, such as municipalities,
counties or states. While practitioners usually want to define the
economy as locally as possible, it is important to keep in mind
that better data becomes more available as we move up the political
hierarchy. Generally, comprehensive data at the sub-county level
is available only every 10 years from the Census. Conversely, state,
national, and even some county data is often updated monthly.
Once you have defined your economy, you can
use these tools to size up your economy, keeping in mind the principles
outlined above.
Read Me First! An Introduction to the
Industry and Employment Classification System
The Industrial Classification system is a basic framework for categorizing
establishments, and serves as the baseis for regional economic analysis.
Today, much of the readily available economic data related to employment
is based on such classifications.
Tool 1: Develop a "Snapshot"
of Important Local Economic Indicators
A snapshot provides a basic overview of important economic indicators.
Usually, these snapshots are presented as a series of tables and
charts.
Tool 2: Chart the Historical Perfomance
of Key Economic Indicators
Tracking the performance of key economic indicators over time can
help you identify growing and declining sectors. Trend analysis
can also be used to identify new opportunities.
Tool 3: Use Location Quotients to Identify
Local Strengths and Opportunities
The location quotient helps you identify those local industries
that are producing more than is needed for local use and selling
outside the region (exporting) and those that are not meeting local
needs and are a source of consumption leakage (importing).
Tool 4: Shift-share Analysis Helps Identify
Local Growth Engines
Separating the role of local and national effects on current regional
employment trends has long bedeviled many community development
practitioners. Shift-share analysis is one useful tool for overcoming
this challenge.
Warren Kriesel, an economist at the University of Georgia, has
developed a web-based
dataset for interactive shift-share analysis . It uses the
database in the U.S. Bureau of Economic Analysis' Regional Economic
Information System, for the years 1980 through 1999. You can do
the analysis for a single county, a group of counties, or whole
states. Very cool!
Tool 5. A Pennsylvania Internet Resource
for Industry Employment and Occupation Projections
CWIA has developed extensive capabilities in addressing questions
about future employment growth. Working in conjunction with a national
consortium sponsored by the Employment and Training Administration
at the U.S. Department of Labor CWIA provides industry employment
and occupation projections for both the short- and long-term. The
overarching goal of the initiative is to present key labor market
facts so that all job seekers looking for quick entry into the labor
market can make informed job choices.
Tool 6: Qualitative Analysis Can Provide
Unique Insights into Local Economic Performance
Because they provide insights into local trends that may not be
measurable, practitioners may find qualitative assessments of the
local economy are a useful complement to the quantitative tools
described elsewhere in this series. Alternatively, qualitative analysis
can be seen as a way to tap into local expertise, thus providing
information on the local economy that does not appear in official
statistics.
Some Basic Local Economic Indicators
In this section we discuss some potential
indicators you may want to consider. Web sources of data are provided.
This list is far from comprehensive!
Unemployment Rate
The Bureau of Labor Statistics provides monthly
estimates of county unemployment rates for states, metropolitan
areas and counties. The unemployment rate is easy to calculate:
it is the number of people who are jobless and available for work
divided by the labor force. The basic concepts involved in identifying
the employed and unemployed are quite simple:
People with jobs are employed.
People who are jobless, looking for jobs, and available for work
are unemployed.
People who are neither employed nor unemployed are not in the
labor force.
Employment
The employment data is a complete measure
of the number of full- and part-time jobs in the county. Historical
state and county data from 1969-1999 is available the Bureau of
Economic Analysis. The employment data include wage and salary workers,
proprietors, private household employees and miscellaneous workers.
Because part-time workers are included, a person holding two part-time
jobs would be included twice. The Appendix provides details of sectors
covered under each broad industry.
Earnings
Earnings of employees is the sum of wages
and salaries, other labor income (e.g., benefits) and proprietors'
income. As with employment, data are from the Bureau of Economic
Analysis. Also, like employment data, earnings data are by place
of work, so that earnings of an employee who works in one county
but resides in another are counted in the county where the job is.
Earnings per worker are simply the total earnings in an industry
divided by total number of employees.
Population
Historical population data is available from
the US Dept of Commerce, Bureau of the Census. When analyzing local
economies, population growth trends are often used as a crude measure
of relative economic performance. Typically, areas with rapidly
growing populations also have strong job growth.
Per
Capita Personal Income
Personal income is the income people receive
from all sources?-that is, from working, from transfer payments,
and from interest and investments. Per Capita Income is the total
personal income of the residents of a given area divided by the
resident population of the area. Per capita personal income is often
used as an indicator of the quality of consumer markets and of the
economic well?being of the residents of an area. The Census Bureau
provides Per Capita Income County data every ten years for every
municipality. Annual state and county-level estimates are available
from the Bureau of Economic Analysis.
Building
Permits
This data summarizes the number of new housing
units authorized by building permits. The data relate to units intended
for occupancy on a housekeeping basis. They exclude mobile home
units. Building permit data is useful to understand the growth in
residential development in a community (Penn State Cooperative Extension
has produced an on-line workbook for communities to help understand
potential impacts of residential development on government revenues
and expenditures.
Poverty
Rate
This is an estimate of the percentage of the
county population that lives below the poverty threshold, as established
by the Federal government. In providing these estimates, the US
Census Bureau uses a set of money income thresholds that vary by
family size and composition to detect who is poor. If a family's
total income is less than that family's threshold, then that family,
and every individual in it, is considered poor. As an example, the
poverty threshold in 1998 for a family of four (two adults and two
children) was $16,530.
The poverty thresholds do not vary geographically,
but they are updated annually for inflation using the Consumer Price
Index. The official poverty definition counts money income before
taxes and does not include capital gains and non-cash benefits (such
as public housing, Medicaid, and food stamps).
How is this Information Used?
Information gleaned from these tools can be
helpful in several aspects of community development.
For economic development interests, this information
can enhance understanding of employment trends, not only as specific
to the community, but also in context of other regions, the state
or the nation. By identifying growing industries, as well as those
that are declining, local development groups can concentrate their
efforts on industries where the chances of success are greatest.
When applying for community development grants,
it is important to document current and historical conditions. For
non-government organization, using the tools yields information
that can strengthen grant-writing efforts.
Regardless of how you use the data, it is
essential that you present it effectively! While information generated
by the data analysis tools is an important aspect of understanding
the local economy, the fact is that tables and charts are almost
always boring. In order to be effective, you must use the data to
tell a story-don't expect it to be the story.

Another good overview of simple methods is
available source in Community Economic Analysis: A How to Manual.
Published by the North
Central Regional Center for Rural Development, this manual
is designed to assist individuals who need to bring information
to a group of citizens or decision makers concerned with the economic
future of a community. The manual addresses non-local markets linkage,
strategies for economic development, multipliers, assessing the
size and shape of a community's trade area, keeping local dollars
in the community, measuring the efficiency of local firms, and other
strategies.
Other Regional Rural Development Centers and
data depositories include:
Northeast
