Appendixes: This section includes Factbook-related material by topic.

Area: This entry includes three subfields. Total area is the sum of
all land and water areas delimited by international boundaries and/or
coastlines. Land area is the aggregate of all surfaces delimited by
international boundaries and/or coastlines, excluding inland water
bodies (lakes, reservoirs, rivers). Water area is the sum of all water
surfaces delimited by international boundaries and/or coastlines,
including inland water bodies (lakes, reservoirs, rivers).

Area-comparative: This entry provides an area comparison based on
total area equivalents. Most entities are compared with the entire US
or one of the 50 states based on area measurements (1990 revised)

Birth rate: This entry gives the average annual number of births
during a year per 1,000 population at midyear; also known as crude

determining the rate of population growth. It depends on both the
level of fertility and the age structure of the population.

Budget: This entry includes revenues, total expenditures, and capital
expenditures.

Climate: This entry includes a brief description of typical weather
regimes throughout the year.

Coastline: This entry gives the total length of the boundary between
the land area (including islands) and the sea.

information and includes the radio, telephone, and television entries.

Communications-note: This entry includes miscellaneous communications
information of significance not included elsewhere.
