In-Migration and Diphtheria Mortality among Children in the Sundsvall Region during the Epidemics of the 1880s
Bibliographic record
Abstract
While many works have examined urban mortality rates in nineteenth-century Europe, much less attention has been placed on disease patterns in the peripheral areas surrounding these population centers. This study demonstrates that during the Swedish diphtheria epidemic of the early 1880s, mortality rates among children living in the industrial parishes on the outskirts of the town of Sundsvall exceeded those found in the town itself. The epidemic was fueled by the mass in-migration of laborers and their families from distant provinces who sought work in the region's sawmills. Thus, in contrast to the common pattern of disease entering through a port city and spreading into the interior, in this case diphtheria followed the paths of migrants through the rural parishes of the Sundsvall region to the sawmills and then finally into the town itself. This spatial pattern was reversed in the late fall when migrants returned home. Conflicts within the medical profession regarding how best to prevent or contain diphtheria, popular suspicion and distrust of local physicians, and the introduction of the disease into a population with no prior contact with it, all helped increase the number of young corpses.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
