The spatial allocation of population: a review of large-scale gridded population data products and their fitness for use

Population data represent an essential component in studies focusing on human&ndash;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 products, which are of very different characteristics and based on different modeling assumptions, have never been systematically reviewed and compared, which may impede their appropriate use. This article fills this gap and presents, compares and discusses a set of large-scale (global and continental) gridded datasets representing population counts or densities. It focuses on data properties, methodological approaches and relative quality aspects that are important to fully understand the characteristics of the data with regard to the intended uses. Written by the data producers and members of the user community, through the lens of the &ldquo;fitness for use&rdquo; concept, the aim of this paper is to provide potential data users with the knowledge base needed to make informed decisions about the appropriateness of the data products available in relation to the target application and for critical analysis. </div

Visualizing Metadata: Design Principles for Thematic Maps

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 not only suffer from an array of quality problems but also are widely distributed among the general public in cartographic format. Metadata diagrams for thematic maps based on human variables therefore must be clear and concise, so as to be comprehensible by the non-specialist. Principles of good metadata diagram creation are proposed, with attention to the balance between clarity and space constraints

The Geography of Indigenous Identity in the United States

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 that the total enumerated indigenous or partly indigenous population in 2000 was more than twice the size of the reported population in 1990. The intensity of indigenous identification among American Indians (measured by the share of indigenous people who claim a single racial identity) varied geographically, with higher levels on and near reservations and in western states. The core (one-race) population was much more spatially clustered than the peripheral (multi-race) population.Géographie de l'identité autochtone aux États-Unis. Lors du recensement 2000, les Américains ont eu, pour la première fois, la possibilité de choisir plus qu'une identification « raciale ». Les populations indigènes ont manifesté un taux d'identification multiraciale plus élevé que tout autre groupe. Le nombre élevé d'individus ayant exprimé une appartenance partielle aux nations indiennes, couplé à un moindre sous-comptage qu'en 1990, ont conduit à un doublement statistique de la population indienne entre 1990 et 2000. L'intensité de l'identification indigène au sein des Indiens d'Amérique (mesurée par le pourcentage de personnes s'identifiant comme 100 % indiennes) varie géographiquement, avec les taux maxima dans les réserves indiennes et les États de l'Ouest. Le cœur de la population indienne (identification unique) est éclaté en plusieurs noyaux spatialement distincts, alors que la « périphérie » indienne (appartenances ethniques multiples) est présente en de larges portions du territoireComenetz Joshua.

National Jewish Population Map by County

This polygon shapefile contains estimates of the number of Jewish persons in the U.S. by county in 2010 census geographies, based upon multiple sources of data, including Jewish community studies available at the Jewish Data Bank, the Data Bank's Current Jewish Population Report series, and the American Community Survey. Joshua Comenetz used indicators like language spoken and ancestry in the absence of standard demographic data to measure Jewish populations. For more information on the methodology used to compile this data set, see the Jewish Data Bank

The Gender Gap in Education in Eritrea in 1991-1998

This paper shows that during the 1990s, and before the 1998-2000 border war with Eritrea, the gender gap in education in Eritrea has widened on the national level, and large regional disparities have persisted. The gender gap appears to be linked to lower female teacher participation and limited employment opportunities. The widening of the gender gap is likely to have a long-term negative impact on both economic growth and poverty reduction.Poverty reduction;gender gap, girls, female teachers, female education, enrollment rates, elementary schools, female enrollment, gross enrollment, enrollment rate, school enrollment, female students, primary school, primary education, gross enrollment rates, regional education, family planning, gross enrollments, basic literacy, gender inequality, primary school enrollment, education sector, genital mutilation, female employment, barriers to girls ? education, policy research report on gender, school teaching, female labor force participation, female labor, universal education, women in education, gender equality, universal primary education, role of women, female labor force, elementary education, educational attainment, sex discrimination, gender disparities, gender gaps, enrollment data, affirmative action, access of women, school-age children, access of girls, elementary school students, school-age population, sexes, gender inequalities, children per woman, advancement of women, height for age, gender differences, female genital mutilation, gender equality in rights, gender relations, teenage pregnancy, marriage laws, economic situation of women, female poverty, illiteracy rate, net enrollment, elementary school teachers, school teachers, pregnancy, gross primary school enrollment, primary school education, female student
