Population Density, Australia 2011 (ABS)

This data set contains the Australian Bureau of Statistics population data for Australian states and territories. Population data was collected as part of national census’ in 1991, 1996, 2001, 2006 and 2011. Data presented is the total population for all collection districts by place of enumeration. District Boundaries differed for each census and therefore were re-projected onto the 2011 population mesh blocks to standardise the spatial extent of the reporting areas. Given the focus of this project, population data was clipped by a 50km coastal buffer. \n\nNote: population data for census’ 1991 – 1996 - 2001 was purchased by NESP and is made publically available through by NESP\n\nNote: population data for 2006 and 2011 was downloaded through the ABS webportal. \nhttp://www.abs.gov.au/websitedbs/censushome.nsf/home/tablebuilder?opendocument&navpos=240\n\nNote. 2006 Census district boundaries were downloaded from the ABS website\nhttp://www.abs.gov.au/AUSSTATS/abs@.nsf/Lookup/2919.0.55.001Main+Features1Aug%202006?OpenDocument\nand 2011 population mesh blocks\nhttp://www.abs.gov.au/ausstats/abs@.nsf/mf/1270.0.55.001\n\n\nThis data contains geographical information in shape files that represent the population density in Australia, from 1991 to 2011. The data contains the summary polygon, state_code, cd_code19, 91_pop_dat (population count), area and density (in persons per km^2). For other data sets the count will be 96_pop_dat, 2001_pop_dat, 2006_pop_dat and 2011_pop_dat.

本数据集收录澳大利亚统计局（Australian Bureau of Statistics）发布的澳大利亚各州及领地人口统计数据。人口数据采集自1991、1996、2001、2006及2011年五次全国人口普查。本次发布的数据为各普查采集区域按普查登记地点统计的总人口数。由于历次普查的区域边界存在差异，因此已将所有边界重新投影至2011年人口网格块（population mesh blocks），以统一报告区域的空间范围。结合本项目的研究重点，已通过50公里海岸缓冲区对人口数据进行空间裁剪。

注：1991年、1996年及2001年普查的人口数据由NESP采购，并由其公开发布。

本数据集包含以Shapefile格式存储的1991年至2011年澳大利亚人口密度地理信息。数据包含汇总多边形、state_code、cd_code19、91_pop_dat（人口计数）、面积及人口密度（单位：人/平方千米）。其余普查年份的人口计数字段依次为96_pop_dat、2001_pop_dat、2006_pop_dat及2011_pop_dat。
