Finding Government Statistics
Finding government statistics can be a challenging process, requiring unique search strategies. As with any reference question, when in doubt ask for assistance at the YRL Reference Desk. Reference staff can assist you with most statistical searches or refer you to a specialist within the department. The vast majority of statistical publications are produced by governments, so this guide will cover most of your statistical needs. See Step 5 for some tips on expanding your search to cover non-government statistics.
Overview
- Step 1) Define the parameters: variables, time, geography, format.
- Step 2) Consult likely high-use statistical sources. If no luck, move to.
- Step 3) Consult Statistical Universe. If no luck, move to.
- Step 4) Consult statistical guides and/or guides to government documents. If no luck, move to.
- Step 5) Consult non-government sources.
Step 1) Define the Parameters
Define exactly what numbers you need. It sometimes helps to actually draw a sample portion of the table you expect to find. What are the labels on the columns and rows? What type of numbers do you expect to see in the middle? Statistics can be defined by the following parameters:
- Subjects: The things you want to count. Be as specific as possible, including whether you want tables cross-tabulated by sex, age, race, or some other subject. Also, decide whether you need your subject broken down into specific categories. For example, if you want to find Race data, what racial categories do you want to use? See Step 2 below for examples of typical subjects available. "
- Time: What time period should the statistics cover? Are you looking for data over time? The most recent year? It is important to remember there is usually a lag between data collection and publication. For example, the Census is conducted every tenth year, but the data is released 3-5 years later after it's compiled. In many cases up-to-the-minute statistics are not available. Also note that most government statistics provide snapshots, not historical time series, so you may have to look in multiple volumes to get data over time. "
- Geography: What geographic area do you want the statistics to cover? Typical geographic areas include nations, states/provinces, regions, metropolitan areas, counties, and cities. Statistics for small areas (neighborhoods, zip codes, or census tracts) present unique challenges - see Statistics for Community Analysis. "
- Format: This is most important for data since the 1990's, which is often available in both digital and paper formats. Before that time paper is typically the only option, while for anything in the last year or two digital formats predominate. Do you want raw data or aggregate data?
- Availability:Keep in mind that sometimes the statistics or data that are being requested may not be collected and published in the way that person wants, for example, there are a number of demographic, economic, and social characteristics collected by the Census; but they do not necessarily cross tabulate the exact variables. Using raw data one would be able to do this.
Step2) Consult Likely High-Use Sources
- Compilations
- International Compilations
- Demographics
- Housing
- Vital Statistics
- Economics - Businesses
- Labor
- Prices and Consumer Expenditures
- U.S. Foreign Trade
- International Trade and Finance
- Crime and Justice
- Education
- Health
- Transportation
Compilations
These sources gather statistics from many places, and thus have a broad range of topics available. Most also list the original sources and thus serve a secondary purpose as statistical indexes - if you finds a table that's close to your needs but not quite exact, you can usually track the data back to the original, and hopefully more detailed, source.
- Statistical Abstract of the United States.The primary place to look for statistics of almost any
kind about the U.S. and the states. Very limited coverage at the county or city levels. Most tables
cover a few years of time.

- County and City Data Book.This source violates the "variable-orientation" of most government statistics
and gathers a whole lot of variables about a single county or city in one place.
It's only published every five or six years (the latest is 2000), but is updated
annually by a privately-published version.

copies can be found using the UCLA Library Catalog, but since titles vary
it's often easiest just to look on the shelves in the YRL Reference Reading
Room between HA 741 and HA 4736. The call number sequence is organized by
region, beginning with North America, followed by Central America, the Caribbean,
South America, Europe, Asia, Africa, Oceania. Older volumes are shelved
by the same call numbers in the YRL Stacks.

Demographics
Population counts and general characteristics like race, age, and sex. They often also include socioeconomic information about individuals and families.
- [Decennial Censuses]. The most comprehensive
source of U.S. demographic data, including extremely detailed geographic breakdowns. For the last few
decades, see
- Guide to 2000 Census Data
- Guide to 1990 Census Data
- For earlier years, most of the data is in paper. Look at the volumes and their tables of contents to see what's available. YRL Reference Reading Room, Decennial Census Publications [HA 202 year]
- Current Population Reports. The CPRs are a
collection of numbered series based on the Census Bureau's annual Current Population Survey. They provide
counts, estimates, and projections for years between the decennial censuses, but with far fewer variables
and for much larger geographic areas (usually states or regions, rarely counties or metropolitan areas).
- online index, with links to those available online http://www.lib.ohio-state.edu/refweb/govdocs/CPR/CPRindex.htm

Housing
Unit counts, housing costs, tenancy, vacancies, types of housing, housing features. Note that many detailed housing statistics are also covered by the decennial census, which is technically called the Census of Population and Housing. In digital census materials the population and housing statistics are combined, but in paper products the housing reports are usually printed (and shelved) separately. Use the UCLA Library Catalog to find these volumes.
- American Housing Survey. National
data is collected every other year, and data for each of 46 selected Metropolitan
Areas are collected about every four years. RIS keeps the most recent national
summary and the most recent volume for each metropolitan area; older volumes
are in the stacks. You can find the individual volumes in the UCLA Library
Catalog, but it's often easier to just scan the shelves.

Vital Statistics
Births and deaths. These used to be counted as part of the decennial census, but since 1938 there's been a separate annual report. Note that print volumes are woefully out of date, and even the electronic sources tend to be three to four years behind.

Economics - Businesses
Number and type of businesses, number of employees, payroll, sales, and profits. Businesses are typically categorized by industrial classification codes. Until 1997, most sources used the Standard Industrial Classification (SIC) codes. After that, they switched to the North American Industrial Classification System (NAICS). The Census Bureau Home Page (see above) has a "bridge" showing the relationships between the two. Note also that sales statistics are available only for types of business, not for types of products.

- Health Resources and Services Administration
- Statistical Resources on the Web: Health (from University of Michigan)
Transportation
Transportation statistics are primarily collected by the Transportation Department and it's various administrations and boards and the Census Bureau (i.e. journey to work data). For data on specific modes of transportation like air, water, ground, or for a topic like accidents, consult the appropriate transportation administration or use Lexis Nexis Statistical.

Step 3) Consult Lexis Nexis Statistical
There are two ways to search for information in Lexis Nexis Statistical:
- Power Tables
- Retrieve statistical tables (like those you would find in the Statistical Abstract) as well as links to the publication abstracts from the tables are derived.
- Content:
- 130,000 tables indexed annually; 200 Federal Agencies / 50 State Governments / 100 International Intergovernmental Organizations / 500 Private/Academic sources
- Dates: 1997 to the present
- Abstracts
- Retrieve abstracts of articles, reports, and publications that include statistical data.
- Dates: 1974 to the present
- Abstracts include title, date, issuing agency, collation, periodicity. Large publications or publications within in a series are analyzed.
- Tips:
- Use the "Subject List" to search for your topic, rather than using just keywords
- Use the "How Do I" section to help you with specific statistical searches, like budget, revenue, cost of living, crime, etc.
- Look up titles in the UCLA Library Catalog, as we get a many on deposit.
- Lexis Nexis Statistical consists of 3 indexes, ASI, IIS, and SRI. Use the accompanying microfiche sets to access publications that we do not have in print. *NOTE: ASI and IIS are located in the MGI Reading Room at YRL / SRI are located at the Management Library
Step 4) Consult Statistical Guides
- Statistical Resources on the Web (from University of Michigan Documents Center)
- Comprehensive resource for finding statistical publications and sources from government agencies on a wide variety of topics
- http://www.lib.umich.edu/govdocs/stats.html
- Finding Government Information Sources: Electronic and Print. 3rd Edition.
- The Statistical Search, Chapters 28 thru 44, cover a variety of techniques for specific statistical questions.
- YRL Reference Desk Core Z1223.Z7 S4 2001
- Government Statistics from the Government Documents Roundtable
- Google Unclesam
- Searches only .gov and .mil websites at the federal and state levels.
- http://www.google.com/unclesam
Statistics the Government Does NOT Collect
For a significant number of users, you will discover that the specific statistics they want are not collected by the government. There's still a chance you'll find it in non-government sources, but be aware that non-government statistics are usually drawn from small samples, have little geographic detail, may be sporadic in time coverage, are often based on estimates of unknown accuracy, and may be of questionable objectivity. Some commonly found examples are:
- Religion
- Some older censuses (19th century) asked religious affiliation, and you can probably find statistics on numbers of churches. Other than that you'll need to rely on non-government sources.
- Voting
- A surprising number of users don't realize that the U.S. employs a secret ballot! The federal government has statistics on what votes were cast, plus demographic statistics about registered voters, but nothing that links the two. Consult exit polls.
- Detailed Household Expenditures
- The government tracks how much families spend on big categories like food, rent, and entertainment. They don't track how much families spends on meat, curtains, or home videos. Try industry statistical studies in Management or L.A. Public.
- Product Sales
- Unless it crosses the border (see U.S. Foreign Trade, above), the government keeps no records on the manufacture, transport, or sale of individual products. Again, try industry statistical studies.
Step 5) Consult the Academic Literature & Referrals
Use journal articles to track down statistics or to find studies that have original data that is not collected by the government. Some suggested starting points:
- America History and Life
- Expanded Academic
- ERIC (via Cambridge Scientific Abstracts)
- GPO Access via FirstSearch
- PAIS International
You can always come to the Young Research Library Reference Desk for assistance. Also, the government information subject specialists are available for research consultations.

Statistics Glossary
Government statistics often use a variety of terms in very specialized ways. Some things to watch out for:
- Economic Statistics vs. Socio-economic Statistics:
- Economic statistics refer to businesses. Socio-econoimc statistics refer to individuals, households, and families.
- FIPS
- FIPS codes (Federal Information Processing Standards) are used for a variety of things, but the ones most commony seen are the geographic codes for states, counties, and cities. For example, California is 06 and Los Angeles County is 037 (or 06037).
- GDP vs. GNP:
- Gross Domestic Product s a measure of all goods and services produced in the U.S. GNP is the same measure with allowances for depreciation, sales, and property tax. GDP is now usually used as the standard measure in the United States, whereas GNP was used in the past. GDP has always been the more commonly used number in international and foreign statistical sources.
- NAICS vs. SIC
- Traditionally, the U.S. government has classified all businesses using Standard Industrial Classification (SIC) codes. However, in 1997 they began using the North American Industry Classification System (NAICS). While there are often direct correspondences between the two code systems, that isn't always the case. For example, NAICS is far more detailed when it comes to service and information industries. You can find correspondence tables and definitions at http://www.census.gov/epcd/www/naics.html
- Both SIC and NAICS codes are hierarchical in nature. The first two digits represent a broad industry category, and each digit afterwards represents a sub-division. For example, 44-45 = Retail Trade, 445 = Food and Beverage Stores, 4452 = Specialty Food Stores, and 44523 = Fruit and Vegetable Markets.
- Harmonized Tariff Schedule and Schedule B: Harmonized Schedule
- (HS) codes are 6-digit codes used by all countries to define products for export and import. Each 2 digits represents a hierarchical level of classification. (Periods are often placed at certain points to make the numbers easier to read.)
- For example, 01 = Live animals, 0103 = Cows, and 0102.10 = Purebred-breeding cows. Schedule B codes are four digit codes tacked onto the end of the 6-digit HS codes to provide more detail. Each country has its own Schedule B codes, so they're usually used only for exports. Continuing with the example above, 0102.10.0020 = Female dairy cows.
- Canada, Mexico, and the United States are developing a new set of product codes called NAPCS (North American Product Classification System), but these have not yet been implemented in any statistical publications.
- Occupation vs. Industry:
- Occupation refers to the type of job an individual holds.
- Industry refers to the type of business.
- The two don't necessarily coincide. For example, a Computer Programmer may work for an Advertising Agency, and an Advertising Sales Agent may work for a Software Publisher.
- Occupations can be classified by one of two systems, Census Industry and Occupational Classification System categories(which can vary from census to census) and Standard Occupational Classification (SOC) categories (developed by the Department of Labor). Though both of these systems are associated with code numbers, most statistical sources will actually write out the full occupation title so there's no need to know the codes.
