Abstract: Kyrgyzstan serves as a key case study for the broader Central Asia–Russia labor pipeline, which supported an estimated 8 million migrants annually in 2020. Prior to the Russo-Ukraine war, remittances from Russia accounted for approximately 30% of Kyrgyzstan’s GDP, driven by over 10% of its population working in Russia. However, understanding wartime migration dynamics is challenging due to suspected political interference in Russian data, restricted foreign access to this data, and the informality that characterizes Central Asian migration patterns. This study incorporates Yandex Wordstat, Google Trends, XGBoost (which outperforms other machine learning methods), and autoregressive models to "nowcast" missing data. The results reveal a push effect linked to war onset in February 2022 and war intensity. However, all three of the analyzed migration datasets suggest a potential delayed labor substitution effect as Central Asian migrants fill vacancies left by conscripted Russian workers, proxied by casualty data from Mediazona and the BBC. The study also examines remittance trends, which seem to increase along with the labor substitution effect after a two-month lag. These results are robust to Russia- and Kyrgyzstan-side socioeconomic controls such as wage levels and population dynamics. This study provides new insight into the largely opaque Central Asia–Russia labor pipeline, a critical element in development policymaking for both regions. It also introduces a novel methodology for nowcasting migration trends, particularly through Yandex Wordstat, which has been largely overlooked in English-language scholarship.
