Italian National Statistical
Institute Registration data
The data from the Italian National Statistical Institute was originally
supplied to geographers at the Universtiy of Leeds for research concerned
with internal migration within the EU. The source data are points with
population values, these are Registration zone centroids and their respective
population values. Synthetic registration zones were constructed from the
point data using ArcInfo's THEISSEN polygon command. Obviously there will
be a difference between actual registration zone boundaries and the synthetic
ones generated, but hopefully these are only small.
Many thanks to Aldo Orasi (Chief of the Population Census Service) and
Valerio Terra Abrami (responsible for the Demographic Structure and Dynamics
Service) of the Italian National Statistical Institute for the swift provision
of the point dataset.
