Abstract

fetched live from OpenAlex

The release of the latest Census data reveals that Cleveland’s population has fallen since the last census and dipped below the 400,000 mark. From 2000 to 2010, the city’s population fell from around 478,000 to about 397,000 (a 17.1 percent drop). Cleveland’s recent loss of population is not uncommon for cities in the Great Lakes region. Even the largest city in the region, Chicago, has shrunk over the past 10 years. Chicago’s population fell to about 2.7 million in the latest census, a 6.9 percent drop from 2000. Interestingly, both cities experienced their peak population in 1950. Since then, Cleveland has lost over half of its population, while Chicago has lost slightly more than a quarter.

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.

Not 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.
