(Dyadic-driven) Monadic Migration Update To (Hopefully) Address Excess Population Declines #336

Closed caleb-petry closed 3 days ago

caleb-petry commented 2 months ago

This issue will be addressed following the monadic updates from WPP2024.

We have three main assumption options:

  1. Constant Flow (preferred constant when populations increase globally)
  2. Constant Rate (may work better for the Albanias of the world)
  3. Model-based projections (finding a way to better incorporate WPP's newer probabilistic projections; this could be easy, but I have yet to think too much about it; Preferred if possible.)

Data have been updated, however, my understanding is that there are two obvious issues-

  1. There is an incompatibility between WPP2024 and Guy Abel data.
  2. 2020 might not be a good base year for migration due to Covid (check the latest monadic data for India and US)

The data was update, and after tinkering a little with the algoright for balancing dyadic with monadic, we implemented a convergence to 0 of rates from 2100 to 2200. This is how MIGRATE(ALL) now looks:
