Population data represent an essential component in studies focusing on human–nature interrelationships, disaster risk assessment and environmental health. Several recent efforts have produced global- and continental-extent gridded population data which are becoming increasingly popular among various research communities. However, these data produc...

A gridded population dataset was produced for Pakistan by developing an algorithm that distributed population either on the basis of per-pixel built-up area fraction or the per-pixel value of a weighted population likelihood layer. Per-pixel built-up area fraction was calculated using a classification and regression trees (CART) methodology integra...

Previous research on the relationship between impervious surfaces and population has focused on limited areas. This paper considers the relationship for an entire country. Multiple spatial resolution optical imagery was integrated with census data to refine the spatial distribution of population in Haiti. A classification and regression tree (CART)...

This paper maps and estimates the size of the American Hasidic Jewish population by combining census data on age, home language, and race with geographical and demographic-data obtained from previous studies. Though lower than previous figures, the population estimates are consistent with the spatial structure of the community. The accuracy of the...

Maps and graphs that are produced for spreadsheet and GIS software can be customized using Golden Software's Grafher 6 that has a Graph Wizard. Grapher's workspace is well organized, with an Object Manager that displays all elements of current graphs besides the graphics window, making it easy to select graphic elements that are layered below other...

Mental image and place-preference maps of college students in Florida were created through a two-part lesson. The patterns revealed by these maps were linked to students' fife experiences, census data on migration and income, and similar studies conducted in other states. Students prefer states with established migration links to Florida and better...

This paper argues that the best way to transmit metadata to thematic map users is through cartography rather than text notes or digital means. Indicators such as reliability diagrams, common on maps derived from air photos or satellite images, are rarely included on thematic maps based on the census or other socioeconomic data sources. These data n...

GeoLytics, Inc. has helped geospatial users, businesses, academics, non-profits, and government agencies find and navigate U.S. Census Bureau data. The company publishes detailed demographic and geographic data on CD-ROM, packaged with software for searching and extracting the information. Specifically, the company's CensusCDs are perhaps its best-...

The obstacles encourtered in using GIS to create new districts for electing city commissioners were discussed. It was observed that the contiguity is easy to establish in the GIS environment. Although GIS software eased some aspects of redistricting but it could not represent a major time savings with respect to using manual methods and spreadsheet...

The Mapitude Table Chooser from Caliper Corporation that provides access to the complete U.S. Census 2000 SF1 and SF3 is discussed. It requires Maptitude geographical information systems (GIS) version 4.5 or higher. The Maptitude GIS and Maptitude Table Chooser require an Intel Pentium processor, Microsoft Windows 98, NT, 2000 or XP operating syste...

The Sanders housing lawsuit in Pennsylvania provides a case study of how to incorporate current events into the teaching of cartography or population geography at the high school or college level. Settlement of the Sanders case resulted in the release of information about the segregation of public housing by race in the Pittsburgh area. The issues...

In the 2000 census, Americans were allowed to choose more than one "racial" group for the first time. Indigenous people had a higher rate of multiracial identification than other population groups. The larger number of people who identify as partly indigenous, along with the reduction in the level of undercount compared with the 1990 census, means...

El Niño events from the 1970s through the 1990s caused extended droughts in Ethiopia. These droughts were followed by famine and political turmoil that resulted in radical changes of government, secession, and a massive program of population redistribution. Cartographic analysis of Ethiopian census data from 1984 and 1994 shows changes in demograph...

The standard model of the geometry of cartographic visualization in geographic information systems (GISs) is based on the classification of cartographic objects into points, lines, and polygons, represented with zero-, one-, and two-dimensional symbols. This is restrictive because an object or symbol may actually span more than one of these dimensi...

This paper investigates how information affect voting behaviour. There exist a large literature suggesting that uninformed voters can use informational shortcuts or cues to vote as if they were informed. This paper tests this hypothesis using unique Swedish individual survey data on the preferences of both politicians and voters. I find that uninfo...

Timely provision of maps tied to subnational demographic information is critical for improving the efficiency of humanitarian relief efforts during and after natural disasters, conflicts, and other crises. Gathering maps and data after an event is time-consuming, especially when an event affects multiple countries. Despite the demand, a global data...
