Replication data for \"MAKING COUNTRIES SMALL: THE NATIONALIZATION OF DISTRICTS IN THE UNITED STATES\"

I rely on data from 31,754 electoral districts in the United States from 1834 until 2016 to explore how the nationalization of politics occurs within districts. I argue that in the early stages of the American democracy local concerns were more prominent in the distant districts from the capital city than in the nearby districts, and therefore the number of parties was greater in the former than in the latter. However, these differences vanished after the New Deal, when authority was centralized. Nationalization reduced the number of parties everywhere, but above all in the most distant district from Washington, D.C.本研究采用1834年至2016年美国31754个选区的选举数据，探究政治全国化在各选区内的发生逻辑。研究提出，在美国民主发展初期，相较于邻近首都的选区，远离首都的选区更侧重地方议题，因此前者的政党数量多于后者。但在罗斯福新政实施后，随着权力向中央集中，此类差异逐渐消解。政治全国化进程使得各地政党数量均出现缩减，其中尤以距离华盛顿特区最远的选区降幅最为突出。
