DEFINITION
This is one type of single outlet library (SO) or the library which is the operational center of a multiple-outlet library (MO or MA). Usually all processing is centralized here and the principal collections are housed here. Synonymous with main library.
Note: Each public library system (administrative entity) may report either no central library or one central library. No administrative entity may report more than one central library. Where two or more libraries are considered "centrals" for state or local purposes, one central library and one or more branch libraries is reported in the survey. The library identified as the central library is the library with the largest collection; all others are reported as branches. Where there are several co-equal outlets and no principal collection, all such outlets are reported as branches, not central libraries. Per capita figures expressed per 100,000 population.

A correlation is a statistical measure of similarity between at least two given sets of data. StateMaster's
correlations compare two variables from our database and reveal statistical relationships between them. The percentages
you see represent the strength (or likelihood) that a change in the topic variable is matched by a change in the listed
variables below it. But remember: These correlations do not imply causation, that is, one does not necessarily cause
the other. Also, not all variables contain all states, rather subsets of states matched together.
Outliers have been removed only where they are outside 3 standard deviations of the mean.
Only variable pairs where at least 15 states match for each have been considered.
Strength is given by the correlation coefficient (R squared). It is the fraction of variation in Y that can be attributed to the variation in X. 100% signifies a perfect fit (R squared of 1). The top 50 such stats are displayed
