Geography and mapping give new dimension to study of the Holocaust

"Numerous scholars in recent years have made the horrors of the Holocaust real to the public through various media, including books and memoirs, films, art, photography and museum exhibitions. Anne Kelly Knowles and her collaborators are using a different approach to better understand the genocide: geography and mapping.

More specifically, the researchers are employing historical geographic information systems (GIS), computer programs that store, display, and analyze data of past geographies to gain new insights into how the Nazis implemented the Holocaust, the patterns of events, and the impact of the Holocaust on different places..."

Understanding Geographic Relationships: Geographic Summary Levels

"The third installment of our geographic relationships series discusses geographic summary levels and how American FactFinder uses them to provide tabulated data.

To protect individual privacy, the Census Bureau provides summaries of data for geographic areas. For example, you cannot find the median household income for a particular house, but you can find the median household income for the census tract or county for where that house is located. Each summary level, identified by a unique three-digit number, represents a different geographic entity for which the Census Bureau summarizes data..."

Guide to State and Local Census Geography

"The first Guide to State and Local Census Geography (1990 CPH-I-18) was issued in June 1993 as a joint venture between the US Census Bureau and the Association of Public Data Users (APDU). The book contained an overview of census geography and had information about key geographic concepts for each state as it related to the 1990 Census.

The US Census Bureau updated this publication based on geography for the 2010 Census and is making it available as a web publication. The format of this publication is similar to the 1993 publication in that it has information about the census geography of each state..."

Census Bureau's Question & Answers: Population: Geographic Center
What is the geographic center of the U.S. population and how has it changed?
Answer:
"There are a couple ways of describing the geographic center of the U.S. population.:

1. Each decade, the Census Bureau calculates the mean center of population . The center is determined as the place where an imaginary, flat, weightless and rigid map of the United States would balance perfectly if all 281,421,906 residents were of identical weight.

In 1790, it was near Chestertown, Maryland.
In 1880, it was in Covington County, Kentucky.
In 2000, it was in Phelps County, Missouri.

2. Another measure is the median center of the population .

In 1880, it was in Miami County, Ohio.
In 2000, it was in Daviess County, Indiana..."
