资源简介:

Tabular data of population by age groups, race and gender, and the poverty by race 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 2019 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.

POV19_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, 2019. 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、种族与性别划分的人口统计数据,以及按种族划分的贫困数据,附加至拆分普查区地理空间信息中,以此生成整合了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(Census Tract)依据2019年已建城市边界与非建置社区/全县统计区(Countywide Statistical Areas, CSA)边界拆分而来。 ### 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全国人口普查。该局官方网站(https://www.census.gov/)发布了2010年地理边界数据,其中包含普查区数据,用于全美人口统计信息的分析与制图。普查区边界已根据需要进行调整与对齐,以匹配法定城市边界与非建置区域,包括海岸线/沿海区域。 ### 城市边界(City Boundary): 城市边界数据为洛杉矶县的基础底图信息,该数据基于《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。公共工程部提供了最新的城市边界与城市合并形状文件。真实的法定边界仅可由加州持证测量员实地勘测确定。 ### 全县统计区(Countywide Statistical Area, CSA): 该地理区划旨在为非建置区域与洛杉矶市建置区域向县监督委员会汇报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)划定,洛杉矶县企业GIS工作组与县监督委员会非建置区域办公室及外勤代表协作,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汇报用途,而非社区制图,其设计初衷并非精准呈现社区或诸如安吉洛斯国家森林的司法管辖边界。CSA为经董事会批准的地理区划,由按城市边界拆分的普查区块组(Census Block Group)组成。 ### 数据字段说明: CT10:2010年普查区联邦信息处理标准(FIP)代码 FIP19:2019年城市联邦信息处理标准代码 CITY:已建城市名称,非建置区域标注为"Unincorporated"(数据统计基准为2019年7月1日) CSA:全县统计区(CSA)——非建置区域社区名称与洛杉矶市社区名称 CT10FIP19CSA:整合2010年普查区、2019年城市FIP代码的字段,覆盖已建城市、非建置区域与洛杉矶社区 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 POP19_AGE_0_4:2019年0-4岁人口数 POP19_AGE_5_9:2019年5-9岁人口数 POP19_AGE_10_14:2019年10-14岁人口数 POP19_AGE_15_17:2019年15-17岁人口数 POP19_AGE_18_19:2019年18-19岁人口数 POP19_AGE_20_44:2019年20至24岁人口数 POP19_AGE_25_29:2019年25-29岁人口数 POP19_AGE_30_34:2019年30-34岁人口数 POP19_AGE_35_44:2019年35-44岁人口数 POP19_AGE_45_54:2019年45-54岁人口数 POP19_AGE_55_64:2019年55-64岁人口数 POP19_AGE_65_74:2019年65-74岁人口数 POP19_AGE_75_84:2019年75-84岁人口数 POP19_AGE_85_100:2019年85岁及以上人口数 POP19_WHITE:2019年非西班牙裔白人人口数 POP19_BLACK:2019年非西班牙裔非裔美国人人口数 POP19_AIAN:2019年非西班牙裔美国印第安人或阿拉斯加原住民人口数 POP19_ASIAN:2019年非西班牙裔亚裔人口数 POP19_HNPI:2019年非西班牙裔夏威夷原住民或太平洋岛原住民人口数 POP19_HISPANIC:2019年西班牙裔人口数 POP19_MALE:2019年男性人口数 POP19_FEMALE:2019年女性人口数 POV19_WHITE:2019年联邦贫困线以下的非西班牙裔白人人口数 POV19_BLACK:2019年联邦贫困线以下的非西班牙裔非裔美国人人口数 POV19_AIAN:2019年联邦贫困线以下的非西班牙裔美国印第安人或阿拉斯加原住民人口数 POV19_ASIAN:2019年联邦贫困线以下的非西班牙裔亚裔人口数 POV19_HNPI:2019年联邦贫困线以下的非西班牙裔夏威夷原住民或太平洋岛原住民人口数 POV19_HISPANIC:2019年联邦贫困线以下的西班牙裔人口数 POV19_TOTAL:2019年联邦贫困线以下总人口数 POP19_TOTAL:2019年总人口数 AREA_SQMIL:以平方英里为单位的区域面积 POP19_DENSITY:人口密度(人/平方英里) POV19_PERCENT:贫困率。 ### 数据集生成方式: 本数据集将按年龄组、种族群体与性别划分的人口统计数据,以及按种族群体划分的贫困数据,关联至拆分普查区地理空间信息中,以此生成最终数据集。拆分普查区面要素数据通过将2010年普查区面图层、洛杉矶县城市边界面图层与全县统计区(CSA)面图层进行空间相交得到,并尽可能将生成的边界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2019年7月1日。 2. 2010年普查区与2020年普查区划并不一致。同理,城市与社区边界亦会因年度评审与更新而有所差异。
