RAND California Statistical Databases Exercise
Introduction to RAND California Statistics
RAND California (Oviatt Library subscription) includes approximately 100
statistical databases about California. Data is available at various geographic
levels. Some of the databases cover the entire nation.
- From the Library's Home Page, choose Databases
A-Z.
- Find and click on RAND
California. This will take you to the RAND California homepage.
- Type the words "Ventura County" in the SEARCH DATABASE CATEGORIES, VARIABLES,
AND DESCRIPTIONS: box and click on Search. This will generate a list of
the statistical databases in RAND California that have data for the county.
- Use the Back button on the browser to return to the RAND
California homepage. Click on "Search This Website". You get an explanation
of how to search effectively as well as a box to input a keyword search.
Search for "zip code". This generates a list of the statistical databases
in RAND California that have zip code level data.
- Use the Back button on the browser to return to the RAND
California homepage. Click on the STATISTICS button.
- You are now at a menu page that makes it easy to browse the statistical
databases available from RAND California by broad category. Selecting
a category leads to a display of the statistical databases RAND has classified
as belonging in that category. As an example, the category "Community"
leads to 14 databases on crime, parks, population density, housing prices,
traffic congestion/safety, and weather.
- RAND California Statistics
Categories lists information about the statistics available and provides
information on data sources. (This page is a link entitled Statistics
Summary from the RAND
California homepage).
Class Exercise: Find statistics on domestic violence in the City of Los
Angeles
- Go to the RAND California
homepage.
- Use the SEARCH DATABASE CATEGORIES, VARIABLES, AND DESCRIPTIONS box
or "Search this Website", or the STATISTICS button to get to the statistical
database on Domestic Violence Number of Crimes.
- Click in all the boxes for total calls and type of weapon involved.
- Select jurisdiction. Los Angeles City is under "Jurisdictions by county:
I-L". Scroll down the list until you get to Los Angeles County, then click
on Los Angeles. Note that the instructions tell you how to select more than
one jurisdiction if that is what you want. Practice how to do this by finding
CSUN's statistics as well as those for Los Angeles City. If you make a mistake
or change your mind about jurisdictions or some other aspect of the search
and you cannot seem to undo the mistake easily, click on Reset (near the
bottom of the page) to clear the form so you can start over.
- Choose a format. Most frequently used are:
- View Online (HTML table), which displays a table
- Graph (requires JAVA), which displays a line graph online
- Tab delimited (import to spreadsheet), the other format choice,
is useful if you want to import the data into another program (such
as Excel or SSPS).
- Choose a time period. The default is set for as many years as the data
is available.
- Note that you can choose to organize the results by area or category,
which is useful for searches that compare locations. Also, you can increase
the maximum number of hits from 50 up to 500 for searches with many areas
or variables involved.
- Click on Submit. If you want to change your results from an online table
to a graph, click on the Back button, change the format option as appropriate,
and click on Submit. Most graphs offer a button to toggle between value
and index data.
Additional questions to practice using RAND California statistics
Business and Economics
- People often desire information about specific careers. What are the
occupational projections for librarians in Los Angeles and Ventura counties?
- What is the level of office vacancies for Los Angeles suburban areas?
Is this higher or lower than for the downtown area?
- Find the California Gross State Product for the last 20 years. Compare
this, preferably with a graph or chart, to the U.S. Gross National Product

that are poor. (Define poor as on AFDC
or getting free school meals). For this exercise, use zip codes 91324
and 91325 for Northridge. To find out which other zip codes are associated
with Northridge, you could use ZIP Code Look-up, a site linked from Community
Information by Zip Code.
