Abstract
International migration in Latin America today presents several features that will remain constant up to 2030, and new issues will emerge such as the growing feminisation of migration, the special case of indigenous people or human rights aspects. A concentrated migration pattern to the United States and Spain dominate the region. Although this will continue during the next decades, there will also be an incipient pattern of diversification of destinations (other European countries, Canada and Japan). Little progress has been made regarding the productive use of remittances, and the agreements and programmes targeted for temporary labour migration have not become widespread and also continue to include meagre migrant worker quotas. Today, the main destinations for intraregional migrants are Argentina, Costa Rica and the Bolivarian Republic of Venezuela, but there are some modest signs of change in the future.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
