United States annual state-level population estimates from colonization to 1999

The U.S. landscape has undergone substantial changes since Europeans first arrived. Many land use changes are attributable to human activity. Historical data concerning these changes are frequently limited and often difficult to develop. Modeling historical land use changes may be necessary. We develop annual population series from first European settlement to 1999 for all 50 states and Washington D.C. for use in modeling land use trends. Extensive research went into developing the historical data. Linear interpolation was used to complete the series after critically evaluating the appropriateness of linear interpolation versus exponential interpolation.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

自欧洲人首次抵达以来，美国的地貌经历了显著的变迁。众多土地利用的改变可归因于人类活动。关于这些变迁的历史数据往往有限，且开发难度较大。模拟历史上的土地利用变化或许成为必要。本研究从首次欧洲定居至1999年，为美国所有五十个州及华盛顿特区的年度人口系列进行了开发，以供模拟土地利用趋势之用。在开发历史数据的过程中，进行了广泛的研究。经过对线性插值与指数插值适宜性的批判性评估后，采用了线性插值来完成数据系列。该记录摘自美国农业部企业数据目录，该目录为 https://data.gov 目录提供数据。本记录的数据资源包括以下内容：ISO-19139元数据、ArcGIS Hub 数据集、ArcGIS GeoService。欲获取完整信息，请访问 https://data.gov。
