What is in it generally
"County and City Data Book" 1994
Subject content: Over 220 data items for states and counties; almost
200 data items for cities; and 33 items for places of 2,500 or more.
Vintage of data: 1987 through 1992. Examples: age, money and personal

Bureau, other Federal government agencies and private organizations.
The data in this book are organized into four main data tables.
Table A presents 220 data items for the United States as a whole,
each census geographic region and division, and the 50 states and
the District of Columbia. Table B presents for each county and equivalent
area the same 220 data items shown in Table A. Table C presents
194 data items for cities (incorporated places with 25,000 or more
inhabitants in 1990). Table C differs somewhat in content from tables
A and B; as examples, climate data, shown for cities, are not available
for counties and physician data, shown for counties, are not available
for cities. Table D presents 1990 population and two 1990 census
income items for places with 2,500 or more inhabitants in 1990.

the following 12 States: Connecticut, Maine, Massachusetts, Michigan,
Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode
Island, Vermont, and Wisconsin.
Three tables of area rankings are featured in this publication
which highlight various data series. Table 1 presents the top 25
counties in the country for 64 variables along with the United States
total for comparison. Table 2 shows the top county in each state
for 24 different data items. Table 3 presents 36 data items and
rankings for the 77 cities with a 1992 population of 200,000 or

The following terms are also used throughout this publication:
- An average is a number or value that is used to represent
the "typical value" of a group of members. It is a measure
of central tendency for a group of members.
- The mean is an average derived by summing the individual
item values of a particular group and dividing the total by the
number of items, e.g., average travel time to work. It is often
referred to simply as the "mean" or "average".
- The median of a group is the middle number or value when
each item in the group is arranged according to size, e.g., median
household income. It generally has the same number of items above
it or below it.
- A rate is a quantity or amount of an item measured in
relation to a number of units of another item, e.g., the number
of births per 1,000 resident population. The birth rate is obtained
by dividing the number of births for a given year by the resident
population as of a specified date and multiplying the result by
- Per capita is a rate per individual, e.g., per capita

Errors and reliability (1994 "County and City Data Book")
All data from Censuses, surveys, or administrative records are
subject to error arising from a number of factors: sampling variability
(for statistics based on samples), reporting errors in the data
for individual units, incomplete coverage, nonresponse, imputations,
and processing error.
For some items, details may not add to the totals shown: for example,
a State total may differ from the sum of its component counties,
or the United States total may differ from the sum of total 50 States
and the District of Columbia. Rounding of the data may be the reason
for these occurrences, or the total may include values that could
not be allocated to the lower geographic levels shown. Other examples
are generally footnoted in the tables or explained in the text.
The Bureau of the Census can not accept the responsibility for
the accuracy or limitations of the data presented in this publication
other than for those it collects. The responsibility for selection
of the material and for proper presentation, however, rests with
