Angwin and Deer Park

Populations Centers of Angwin and Deer Park areas from the statewide dataset city90a (www.gis.ca.gov). This was used as a graphic for the Baseline Data Report maps along with the other population centers from this layer. The 'CITY90' layer contains 1990 Census Federal place code boundaries that have been clipped by the county tile outline. The Federal place codes define polygons that are cities or census designated places or are unclassified as to type. Updated in 2021 as part of routine maintenance to better fit the boundaries found in the US Census Bureau's 2016 MAF/TIGER database. Data obtained from the California Geographic Places Boundaries dataset (data.ca.gov/dataset/ca-geographic-boundaries).本数据集提取自全州级数据集city90a（www.gis.ca.gov）中的安格温（Angwin）与迪尔帕克（Deer Park）区域人口聚居点数据。该数据曾与该图层内其他人口聚居点一同作为《基线数据报告》地图的配图素材。"CITY90"图层包含经县域瓦片轮廓裁剪后的1990年人口普查联邦地点编码边界，此类编码定义了城市、人口普查指定聚居地或未分类类型的多边形区域。本数据集于2021年作为日常维护的一部分完成更新，以更好地匹配美国人口普查局（US Census Bureau）2016年MAF/TIGER数据库中的边界信息。本数据源自加利福尼亚地理聚居地边界数据集（data.ca.gov/dataset/ca-geographic-boundaries）。
