Sažetak	Chain migration mapping reconstructs the social mechanism by which one migrant's move triggers many others, tracing the kin, friend, and paesani ties along which earlier arrivals recruit and sponsor later ones into the same destination. John and Leatrice MacDonald's 1964 study of Italian migration to the United States gave the process its classic name, showing how chains of personal sponsorship channel newcomers into specific neighborhoods and produce the dense ethnic enclaves that dot immigrant cities. The method treats migration not as independent decisions by isolated individuals but as a self-feeding network in which each settler lowers the cost and risk of moving for those still at home. Douglas Massey's 1990 theory of cumulative causation formalized why such chains accelerate over time, as every new migrant expands the web of contacts that makes the next move easier. Mapping a chain therefore means building the directed sponsorship graph, ordering it by arrival time, and clustering it at the destination to reveal how neighborhoods crystallize. The result is both a descriptive map of who brought whom and an explanatory account of why migration streams persist and concentrate.	Onward migration analysis studies what happens after a migrant's first move: rather than settling permanently or returning home, many migrants move again to a third country or region, a secondary or 'onward' move that conventional origin-to-destination analysis misses entirely. The analytical core is event-history modeling with competing risks. From the moment a migrant arrives at a first destination, several mutually exclusive futures compete — moving onward, returning to the origin, or remaining — and the method models the hazard of each as a function of time since arrival and of the migrant's characteristics and conditions. This framing draws on the step-wise migration tradition that David Conway clarified in 1980, in which migration unfolds as a sequence of moves rather than a single transition, and on the synthesis of migration theories by Massey and colleagues in 1993, which supplies the human-capital, network, and structural mechanisms that drive secondary movement. A central question is selectivity: onward movers are typically not a random subset of arrivals but are differentially selected on skills, legal status, and ties, so comparing the determinants of onward moves against those of return and staying reveals who keeps moving and why.
