This paper focuses on the migration pathways (MP) of individuals from a rural population in the Philippines. The succession of migrations undertaken by an individual and the role of previous migration(s) in subsequent migration have received relatively little attention in migration studies. The present paper fills this knowledge gap by identifying MP types and exploring links between migrations from a life course perspective. It develops a methodological framework based on sequence and graph analysis. Based on research conducted in Bohol (Philippines) using field data, the two methods are jointly used to reveal the diversity of MP. We focused on migrations done between the ages of 15 and 30. Typical MP were identified using hierarchical clustering. Socioeconomic data collected during surveys were used to characterise the types of MP (e.g., gender, education and age). Sequence analysis revealed six types of MP: some are common across the Philippines (e.g., the circular migration towards Mindanao until the 1970s), while others are specific to the area (e.g., permanent migration toward other places in Bohol). Graphs offer alternative representations of MP that allow to consider the shape of both individual and collective MP. The approach developed here is reproducible, easy to implement and contributes to a better understanding of the complexity of migration by looking at the migrants' histories.

使用序列和图表分析探索菲律宾农村人口迁移的复杂性

本文重点关注菲律宾农村人口个体的迁移路径 (MP)。在移民研究中，个人进行的移民的连续性以及先前的移民在随后的移民中的作用相对较少受到关注。本文通过识别 MP 类型并从生命历程的角度探讨迁移之间的联系来填补这一知识空白。它开发了一个基于序列和图分析的方法框架。基于在保和岛（菲律宾）利用现场数据进行的研究，两种方法联合用于揭示 MP 的多样性。我们重点关注 15 岁至 30 岁之间的迁移。使用层次聚类来识别典型 MP。调查期间收集的社会经济数据用于描述议员的类型（例如性别、教育程度和年龄）。序列分析揭示了六种MP类型：一些在菲律宾各地很常见（例如，直到20世纪70年代，向棉兰老岛的循环迁移），而另一些则是该地区特有的（例如，向保和岛其他地方的永久迁移）。图表提供了 MP 的替代表示形式，允许考虑个人和集体 MP 的形状。这里开发的方法可重复、易于实施，并有助于通过观察移民的历史更好地理解移民的复杂性。
