Total fertility rate is the correct metric for comparing how many kids a woman or couple is deciding to have. The birth rate is just boosted by Haredi Jews having outlier amounts of kids, presumably because its a cult where women don’t have many rights.

> Among Jews, the TFR among Haredim has fluctuated around 7 children per woman since the 1980s, and around 2.5 children per woman among the secular and the traditional who identify as not religious. However, Haredi fertility in the 2007 to 2013 period was lower than in the 1990s, while fertility in the non-Haredi Jewish population has increased since then.

>Even among Jewish women who self-identify as secular and traditional but not religious, the combined TFR exceeds 2.2, making it higher than the TFR in all other OECD countries.
