This article analyzes rural–urban migration and subsequent caste/ethnic diversification in Kathmandu Metropolitan City (KMC) using ward-level (the smallest spatial unit) data from Nepal’s National Population and Housing Census 2011 (CBS, 2012). KMC has 975,453 residents with migrants constituting 57 percent of the population. Almost all caste/ethnic groups (122 out of 125 in total) are present in KMC, with Newar, Brahmins and Chhetris as the largest groups. Eighty-six percent of the migrants are rural-urban migrants. Thirty-five percent of all rural–urban migrants in the country are in KMC. In this study, I examine ethnic diversity using the ethnic diversification index (EDI). The index of 83.7 percent reflects the significant role of migration in urbanization. The diversified landscape also demonstrates distance function, educational differentials and regional segregation of migrants.

本文使用尼泊尔 2011 年全国人口和住房普查 (CBS, 2012) 的病房级（最小空间单位）数据分析了加德满都大都市 (KMC) 的城乡迁移和随后的种姓/种族多样化。KMC 有 975,453 名居民，其中流动人口占总人口的 57%。几乎所有种姓/种族群体（总共 125 个中的 122 个）都存在于 KMC，其中 Newar、Brahmins 和 Chhetris 是最大的群体。86% 的流动人口是农村-城市流动人口。该国所有农村-城市移民中有 35% 在 KMC。在这项研究中，我使用种族多样化指数 (EDI) 来检查种族多样性。83.7%的指数反映了移民在城市化中的重要作用。多样化的景观也表现出距离功能，
