| Population
dynamics and distribution are key elements in understanding
not only how and where people make their living, but how human
interactions with the environment affect environmental change.
The National Research Council has identified population dynamics
as a priority area of research for the US Global Change Research
Program. It points out the key role of georeferenced social
data in improving our understanding of land use change and
assessing impacts, vulnerability, and adaptation to global
change (NRC 1994).
US Census
data in Atlas GIS, Arc/Info, and MapInfo format can be obtained
from CIESIN.
More population and global change data sets are available
from the Socioeconomic
Data and Application Center (SEDAC). |

| You will
find that not everything works for every data layer in these
listings. Our efforts at documenting, indexing, and distributing
data are a work in progress. Although we cannot currently
provide all the information you need to locate all data on
this server, we will try to provide as much as possible at
any given stage of a project. |

The
availability of the buttons on this page is a function
of
|
| 1.
The state of completion of documentation and data packaging
for any given layer. The Catalog and the Clearinghouse
will probably never be complete, but as we finish documentation
for existing data sets, and for those that result from
ongoing research projects we will add as much information
to these pages as we can at various stages. |
| 2.
Our ability to distribute the data or the documentation.
CAST does not 'own' all the data sets that reside in
our warehouse. However we want to provide as much information
to the public about these data sets as we can. |
