Clearly it’s a multifaceted issue, but all other things being equal (same culture, same applicable social safety net, etc.), rich people do have more babies than poor countrymates: https://ifstudies.org/blog/more-babies-for-the-rich-the-relationship-between-status-and-children-is-changing
It’s a linear relationship for men, and u-shaped for women (middle-income women have fewer kids than poor women, but high-income women have more kids than middle-income women).
It’s important for vote counts to to be independently checked. Having who voted publicly available means an investigative journalist can prove the county clerk’s claim that dead people voted and so they can’t certify the election is false. Or catch attempts at fraud. Both as a double-check on government in the case of officials who are lying or have acquired false beliefs, or as outside help if the issue isn’t caught internally due to under-resoucing.
