This page https://wage.is/marshall-islands/ claims the average is US$168000 per year and the median US$9600 per year. [My guess is that the poverty line is close to US$5000 per year, probably higher.] This program adds US$800 per year. So it's a "universal partial basic income" instead of a "universal total basic income".

In all the discussion I remember, "universal basic income" == "universal total basic income" but perhaps I was not paying too much attention.

Multiple % of the population live on <$3/day.

This payment is 37% of the poverty line. Poverty has been reduced from 7.2% to 1.3%. https://documents1.worldbank.org/curated/en/0997063042125181...
