The census-data analysis, published by the Asian American Legal Defense and Education Fund, found that in all three Chinatowns, the Asian share of the population dropped steadily between 2000 and 2010, while the white percentage rose.
We used three different approaches: ecological analysis at municipality level, residential cohorts defined from census data, and case control analysis with individual residential histories.
Census data and content analysis of media reports have been used in that regard.
In this study, we used a combination of field surveys, remote sensing, census data and spatial analysis to investigate the interrelationships among geographical and social-economic variables across 328 different urban structural units (USUs) and how they may influence the distributions of urban forest cover, plant diversity and abundance, within the central urban area of Beijing, China.
Using year 2000 U.S. census data and principal components analysis, socioeconomic indices were developed representing a priori – defined domains of education, employment, housing, occupation, poverty and residential stability.
Future studies should try to leverage historical census data to replicate the analysis conducted here, but for a longer time period.
The demographic census data used for this analysis are historical census data; current 2000 census tract delineations are traced backward in time using Geolytics software (http://www.geolytics.com) and the NCDB (Neighborhood Change Database; http://geolytics.com/USCensus,Neighborhood-Change-Database-1970 2000,Products.asp).
We therefore included as a measure of socio-economic status the seven-level deprivation index derived from small-area census data used in our analysis of measured magnetic fields (UKCCS Investigators, 1999).
The new analysis used census data to make projections.
A recent analysis of census data by Urban Institute researchers found that the number of uninsured children jumped by a startling 710,000 last year.
