Gay migration is a popular culture notion that lesbian, gay, and bisexual (LGB) people move from places that are not gay-friendly to places that are gay-friendly. Such migration may reflect person-environment fit, and it may be comparable to other types of person-environment fit that may rely on attitudes. The present research examines psychological mechanisms underlying LGB and straight people's migration in search of fit, based on sexual orientation, sexuality attitudes, and contextual cues to gay friendliness. In Study 1, we leveraged a very large, ecologically valid internet sample to examine real-world migration, and in Study 2, we experimentally manipulated gay culture to examine desire to migrate. Both studies provide evidence for person-environment fit moderated by sexual orientation: LGB people largely migrated to gay-friendly places regardless of their own sexuality attitudes, whereas straight people migrated to places that matched their sexuality attitudes. We discuss the implications of these findings for LGB people's health and well-being, demonstrating the importance of fostering gay culture as it relates to fit and belonging among LGB people.

同性恋移民是一种流行的文化观念，即女同性恋、男同性恋和双性恋 (LGB) 人从对同性恋不友好的地方迁移到对同性恋友好的地方。这种迁移可能反映了人与环境的契合度，并且它可能与可能依赖于态度的其他类型的人-环境匹配相媲美。本研究基于性取向、性态度和对同性恋友好的背景线索，研究了 LGB 和异性恋者为寻求契合而迁移的心理机制。在研究 1 中，我们利用一个非常大的、生态有效的互联网样本来检查现实世界的迁移，而在研究 2 中，我们通过实验操纵同性恋文化来检查迁移的愿望。两项研究都为性取向调节人与环境的契合提供了证据：LGB 人大部分迁移到对同性恋友好的地方，而不管他们自己的性态度如何，而异性恋者迁移到与他们的性态度相匹配的地方。我们讨论了这些发现对 LGB 人的影响
