What are the total fertility rate and contraceptive use by division, in 2022 and over time?

Health surveys: fertility and contraception. Part of what the twin can answer. Every figure below is the value the route serves, with its source; the raw response is at /api/twin/brain/dhs/topic/fertility.

Descriptive, sourced: no model

Basis: sourced records (URL, sha256 or locator per row), no model.

DHS Program API subnational indicators for Bangladesh, 1993-94 to 2022	Publisher: The DHS Program (ICF); surveys by NIPORT, MOHFW	Unit: one row per (survey, indicator, region)	Caveat: Maternal figures use three-year recall in every survey, except the postnatal checkup, which the API carries without a window label; the printed BDHS 2022 maternal tables use two-year recall and differ slightly. Mortality subnational figures exist only for ten years preceding the survey, not the five-year headline the reports print. Anemia was last measured in 2011. Aggregate rows (Chattogram/Sylhet, Dhaka before 2015, Rajshahi/Rangpur) are boundary-change comparators, not divisions.

District figures: DHS is division-level; no district breakdown exists in the pull.
Anemia after 2011: Neither the 2017-18 nor the 2022 survey measured anemia; 2011 division values are served with their survey labelled.
WASH and schooling indicators: They belong to the wash, people and education brains; this route links to them instead of repeating them.
