"The 1980 and 1990 Public Use Microdata Samples (PUMS) of the U.S. Census contained detailed information on individuals in large samples. The incompatible PUMS metropolitan geographies across these census years, however, compromise use of these data. In this note, we discuss a procedure to match the geography of the 100 most populous metropolitan areas in the 1980 and 1990 PUMS. Programmed in SAS, this set of matched metropolitan areas facilitates comparative urban analysis for 1980 and 1900. The code can be downloaded from a website (http://baja.sscnet.ucla.edu/~ellis/metrocode.html)."

The author describes Historical Demography II, an "image-based web presentation (URL: http://userpage.fu-berlin.de/~ethnohis/hd2bkl.htm) which was realised from 1995 to 1997. Dozens of votive pictures from Bavaria [Germany], dating from the early seventeenth century to the present day and accompanied by a multitude of comments, are used to...demonstrate demographically-relevant events or conditions in the areas of pregnancy and birth, human longevity, illnesses and accidents, wars and crimes, dying and death."
