The incidence of annexation, the growth in the original area and in the area annexed, and the proportion of growth due to annexation between 1950 and 1970 are analyzed for U.S. cities grouped by size, metropolitan status, and region of the country. Over this period, annexation was a principal means of population growth for incorporated places outside the Northeast. Though often associated with metropolitan growth, annexation was even more important in the growth of nonmetropolitan cities. Overall growth differences by size of place, metropolitan status, and decade (1950--1960 or 1960--1970) could not be explained by the incidence and nature of annexation.
按规模、大都市地位和所在地区对美国城市进行分组，分析了1950年至1970年间的合并发生率、原城区和合并城区的面积增长情况，以及合并导致的增长比例。在此期间，合并是东北部以外已建制地区人口增长的主要方式。虽然合并常常与大都市的发展相关，但在非大都市城市的发展中，合并更为重要。按城区规模、大都市地位和年代（1950 - 1960年或1960 - 1970年）划分的总体增长差异，无法通过合并的发生率和性质来解释。
