Population of the Border States in the American Civil War 1860-1870

The Border states were the five slave states who did not secede from the Union and did not declare allegiance to either side. Their name comes from the fact that they bordered the free states of the Union to the north, and the slave states of the Confederacy to the south. Generally speaking, the border states supported the Union more often than the Confederacy, however this changed throughout the war. For example, Missouri sent 39 regiments to fight in the siege of Vicksburg: 17 to the Confederacy and 22 to the Union. The involvement of men from these states was also complicated, as family members quite often found themselves on opposing sides of the battlefield. From the graph we can see that, while all states' populations grew, the smaller states had a lower growth rate, as they saw a higher proportion of conflict. Missouri had, by far, the highest growth rate during this decade, due to an increase in westward migration, as well as a lower rate of conflict.

边疆州是指那五个未从联邦分离且未向任何一方宣誓效忠的奴隶州。其名称源于它们北部毗邻联邦的自由州，南部毗邻邦联的奴隶州。总体而言，边疆州对联邦的支持频率高于对邦联的支持，然而这一状况在战争期间有所变化。例如，密苏里州向维克斯堡围攻派遣了39个军团：其中17个支援邦联，22个支援联邦。这些州的民众参与情况亦颇为复杂，因为家庭成员往往发现自己身处战场的对立阵营。从图中可见，尽管所有州的人口均有所增长，但面积较小的州增长速度较低，因为它们见证了更高比例的冲突。在本十年间，密苏里州的增长率遥遥领先，这主要归因于向西迁移的增加以及冲突率的降低。
