Census County to County Migration

County-to-County in-migration, out-migration, net migration, and gross migration data as reported by the US Census Bureau.  Migration is based on residence one year ago.  Data is collected through the American Community Survey monthly data sample, and the county-to-county special tabulation is based on the 5-year ACS estimates.  The year shown in this dataset is the final year of the 5-year data collection period.

该数据集收录了由美国人口普查局报告的县际间移民、净移民和总移民数据。移民统计基于一年前的居住地。数据通过美国社区调查的月度数据样本收集，而县际间特殊统计则基于五年期美国社区调查的估计值。本数据集中所示年份为五年数据收集周期的最后一年。
