Zoning, as a public land-use tool, has several important goals. As zoning accomplishes these goals, however, zoning has had the unintended outcome of guiding high numbers of minorities into certain areas in which multi-family housing is permitted. This study attempts to understand the connection that zoning has with racial and ethnic distribution within and across jurisdictions in the Washington, D.C. MSA. By using GIS to spatially connect zoning districts to Census data, I analyzed correlations between minority populations and zoning district regulations. For all locations studied, I found that proportions of minority population generally increase as zoning districts permit higher-intensity residential uses. Minority populations often increased as the density permitted by zoning districts increased, although there were many exceptions to this trend, most notably in the central city where minority populations did not directly correlate with zoning density. In all cases, however, low-density, single-family zoning districts had higher white populations than other, higher-density zoning districts. Zoning was shown to have the greatest correlation with minority populations in jurisdictions undergoing significant population growth, particularly minority population growth. The study shows that racially-segregated neighborhoods exist across a variety of zoning types, including low-density, single-family districts, but that segregation is more abundant within zoning districts that permit higher-intensity uses and higher-densities. White isolation was found to be greatest in low-density, single-family zoning districts. Although there is a clear connection between zoning regulations and minority population settlement, zoning density does not perfectly correlate with minority population and racially-segregated areas. Many higher-density zoning districts throughout the study area have high white populations and high levels of white clustering. Conversely, high minority populations and minority clustering occur to significant extents in parts of single-family zoning districts, particularly in Washington and Prince George's County. / Master of Urban and Regional Planning

Connection between distribution of socio-economic characteristics of population and economy in relation to railway network in Czechoslovakia in 1921 and 1930 Abstract Transport is closely related with social and economic processes in space and they affect each other. History of transport, and economy and history of the population are themes quite well covered. Attempts to synthetically cover history of transport and society and its activities in the space have not been numerous, if any they only referred to certain examples, although the transport, especially rail, is mentioned as an important factor of development. The diploma thesis analyzes statistical dependece of selected demographic and socioeconomic characteristics of national censuses in 1921 and 1930 and economic characteristics and agriculural units in 1930 on rail infrastructure in the Czechoslovak Republic. The key statistical data are selected census results (eg. age of population, literacy and inhabitans in the sector of the national economy), results of census of economic and agricultural units (for example units equipment) at the level of administrative units in Czechoslovakia. Spatial data (maps) are an important source, too. These allow statistical and visualization operations in the GIS. They had to be digitized in order to create map...

Abstract The thesis deal is to describe disposal age and culture structure people in South Bohemia region of census 2001 to corpora map. At first deals with dilemma of GIS, cartographis means, data by age and culture strukture. The thesis deal dissect peoples structure in South Bohemia region by SLDB 2001. The thesis also contains a chapter with design leaves mapsand map printing. An the end are leaves maps with disposal GIS and commentaries to them.
