资源简介:

Tabular data of population by age groups, race and gender, and the poverty by ethnic groups is attached to the split tract geography to create this split tract with population and poverty data. Split tract data is the product of 2010 census tracts split by 2011 incorporated city boundaries and unincorporated community/countywide statistical areas (CSA) boundaries. The census tract boundaries have been altered and aligned where necessary with legal city boundaries and unincorporated areas, including shoreline/coastal areas. Census Tract: Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution. The Census Bureau (https://www.census.gov/) released 2010 geographic boundaries data including census tracts for the analysis and mapping of demographic information across the United States. City Boundary: City Boundary data is the base map information for the County of Los Angeles. These City Boundaries are based on the Los Angeles County Seamless Cadastral Landbase. The Landbase is jointly maintained by the Los Angeles County Assessor and the Los Angeles County Department of Public Works (DPW). This layer represents current city boundaries within Los Angeles County. The DPW provides the most current shapefiles representing city boundaries and city annexations. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California. Countywide Statistical Areas (CSA): The countywide Statistical Area (CSA) was defined to provide a common geographic boundary for reporting departmental statistics for unincorporated areas and incorporated Los Angeles city to the Board of Supervisors. The CSA boundary and CSA names are established by the CIO and the LA County Enterprise GIS group worked with the Los Angeles County Board of Supervisors Unincorporated Area and Field Deputies that reflect as best as possible the general name preferences of residents and historical names of areas. This data is primarily focused on broad statistics and reporting, not mapping of communities. This data is not designed to perfectly represent communities, nor jurisdictional boundaries such as Angeles National Forest. CSA represent board approved geographies comprised of Census block groups split by cities.

POV11_PERCENT: Poverty percentage. How this data created? The tabular data of population by age groups, by ethnic groups and by gender, and the poverty by ethnic groups is attributed to the split tract geography to create this data. Split tract polygon data is created by intersecting 2010 census tract polygons, LA Country City Boundary polygons and Countywide Statistical Areas (CSA) polygon data. The resulting polygon boundary aligned and matched with the legal city boundary whenever possible. Note: 1. Population and poverty data estimated as of July 1, 2011. 2. 2010 Census tract and 2020 census tracts are not the same. Similarly, city and community boundary are not the same because boundary is reviewed and updated annually.

本数据集将按年龄组、种族与性别划分的表格型数据(tabular data),以及按族群划分的贫困数据,与拆分后的普查区地理空间信息关联,生成包含人口与贫困数据的拆分普查区数据集。拆分普查区数据由2010年普查区(2010 census tracts)按照2011年建制城市边界与非建制社区/全县统计区(Countywide Statistical Areas, CSA)边界拆分而来。必要时,普查区边界已依据法定城市边界与非建制区域(包括海岸线/沿海区域)进行调整与对齐。 普查区(Census Tract):根据美国宪法要求,美国人口普查局每十年开展一次美国人口统计。美国人口普查局(https://www.census.gov/)发布了2010年地理边界数据,其中包含用于全美人口统计信息分析与制图的普查区数据。 城市边界(City Boundary):该数据集的城市边界数据为洛杉矶县的底图信息,其基于洛杉矶县无缝地籍土地基础库(Los Angeles County Seamless Cadastral Landbase)构建。该土地基础库由洛杉矶县评估员办公室与洛杉矶县公共工程部(Department of Public Works, DPW)联合维护。此图层展示了洛杉矶县范围内当前的城市边界。公共工程部提供了反映最新城市边界与城市吞并情况的形状文件(shapefiles)。法定的真实边界仅能由加州持照测量员通过实地勘测确定。 全县统计区(Countywide Statistical Areas, CSA):全县统计区的设立旨在为非建制区域与洛杉矶市建制区域向县监督委员会报送部门统计数据提供统一的地理边界。CSA边界与名称由首席信息官(CIO)确定,洛杉矶县企业地理信息系统(Enterprise GIS)团队与洛杉矶县监督委员会非建制区域及外勤副手合作,尽可能贴合居民的通用命名偏好与区域历史名称。该数据主要服务于宏观统计与报告用途,而非社区制图,其设计初衷并非精准代表社区或诸如Angeles National Forest等司法管辖边界。CSA代表经董事会批准的地理区域,由按城市边界拆分的普查区块组(Census block groups)构成。 数据字段: CT10:2010年普查区FIP(Federal Information Processing Standard)代码 FIP11:2011年城市FIP代码 CITY:建制城市的城市名称,非建制区域标注为"Unincorporated"(数据截至2011年7月1日) CT10FIP11:关联2011年城市FIP代码的2010年普查区,适用于建制城市与非建制区域 SPA12:2012年服务规划区(Service Planning Area, SPA)编号 SPA_NAME:服务规划区名称 HD12:2012年卫生区(Health District, HD)编号 HD_NAME:卫生区名称 POP11_AGE_0_4:2011年0至4岁人口数 POP11_AGE_5_9:2011年5至9岁人口数 POP11_AGE_10_14:2011年10至14岁人口数 POP11_AGE_15_17:2011年15至17岁人口数 POP11_AGE_18_19:2011年18至19岁人口数 POP11_AGE_20_44:2011年20至44岁人口数 POP11_AGE_25_29:2011年25至29岁人口数 POP11_AGE_30_34:2011年30至34岁人口数 POP11_AGE_35_44:2011年35至44岁人口数 POP11_AGE_45_54:2011年45至54岁人口数 POP11_AGE_55_64:2011年55至64岁人口数 POP11_AGE_65_74:2011年65至74岁人口数 POP11_AGE_75_84:2011年75至84岁人口数 POP11_AGE_85_100:2011年85岁及以上人口数 POP11_WHITE:2011年非西班牙裔白人人口数 POP11_BLACK:2011年非西班牙裔非裔美国人人口数 POP11_AIAN:2011年非西班牙裔美国印第安人或阿拉斯加原住民人口数 POP11_ASIAN:2011年非西班牙裔亚裔人口数 POP11_HNPI:2011年非西班牙裔夏威夷原住民或太平洋岛民人口数 POP11_HISPANIC:2011年西班牙裔人口数 POP11_MALE:2011年男性人口数 POP11_FEMALE:2011年女性人口数 POV11_WHITE:2011年家庭收入低于联邦贫困线100%的非西班牙裔白人人口数 POV11_BLACK:2011年家庭收入低于联邦贫困线100%的非西班牙裔非裔美国人人口数 POV11_AIAN:2011年家庭收入低于联邦贫困线100%的非西班牙裔美国印第安人或阿拉斯加原住民人口数 POV11_ASIAN:2011年家庭收入低于联邦贫困线100%的非西班牙裔亚裔人口数 POV11_HNPI:2011年家庭收入低于联邦贫困线100%的非西班牙裔夏威夷原住民或太平洋岛民人口数 POV11_HISPANIC:2011年家庭收入低于联邦贫困线100%的西班牙裔人口数 POV11_TOTAL:2011年家庭收入低于联邦贫困线100%的总人口数 POP11_TOTAL:2011年总人口数 AREA_SQMIL:以平方英里为单位的区域面积 POP11_DENSITY:人口密度(单位:人/平方英里) POV11_PERCENT:贫困率 数据生成方式: 本数据集的表格型人口数据(按年龄组、族群与性别划分)以及族群贫困数据,被关联至拆分后的普查区地理空间信息以生成最终数据集。拆分普查区多边形数据通过将2010年普查区多边形、洛杉矶县城市边界多边形与全县统计区(CSA)多边形数据进行空间相交得到。生成的多边形边界将尽可能与法定城市边界对齐匹配。 备注: 1. 人口与贫困数据的统计基准为2011年7月1日。 2. 2010年普查区与2020年普查区并不完全一致。同理,城市与社区边界也会因每年的审核与更新而存在差异。
