There are three map series that relate to the geographic
entities for which the Census Bureau provides statistics in
the STF 3 (Puerto Rico) CD-ROM.  Copies of these maps will
be reproduced on electrostatic plotters in response to
orders received by Customer Services, Data User Services
Division, Bureau of the Census, Washington, DC  20233 (301)
763-4100.  Census tract/block numbering area outline maps
may be ordered from the Superintendent of Documents, U.S.
Government Printing Office, Washington, DC  20402.

MAP DESCRIPTIONS

County Block Maps--These maps depict each municipio on one
or more map sheets at various scales, depending on the
municipio's areal size and the density of the block pattern.
(Most municipios include multiple map sheets, including
inset maps for densely settled areas.)  The maps display
block numbers and feature identifiers as well as the
boundaries, names, and codes for the legal and statistical
entities in the municipio.  Each municipio includes an index
map sheet that shows the locations of the map sheets
comprising the municipio set.


Census Tract/Block Numbering Area Outline Maps--These
municipio-based maps depict the boundaries and codes of
census tracts or block numbering areas, the features and
feature names underlying the boundaries, and the boundaries
and names of municipios, municipio subdivisions, and places.
Map scales vary to minimize the number of sheets.  The maps
may include one or more insets for densely settled areas.

County Subdivision Map--This map of Puerto Rico depicts the
boundaries and names of all municipios and statistically
equivalent areas, municipio subdivisions, and places.  (The
Census Bureau also will publish sectionalized versions of
these maps in most 1990 census reports.)

TERMINOLOGY

Refer to appendix A for an explanation of the types of
areas.  Two terms used in the legend require explanation:

Asterisk(*)  A symbol following a block number to indicate
the block number is repeated elsewhere in the block or is
shown partially on an adjacent map sheet or on an inset map.

Fishhook(-----)--A map symbol drawn across a physical
feature (creek, brook, etc.) or boundary on census maps to
show that the areas on both sides of the feature or boundary
belong to the same census block.
