Poland
At No. 23, Poland is close to the halfway mark of our richest countries ranking. For Poland, because it is very average in most places, there have been no actual glaring good or bad figures. Its GDP of $585.8 billion recently ranked the world’s No. 21, as well, as its SPI checks in at No. 32. High results in water supply and sanitation, healthcare, and access to basic knowledge give Poland’s SPI a surge. However, its 48.74 scores in access to the best education are relatively modest. At $29,109 annually, earnings ranks No. 43.

New Zealand
Albeit not as important as Luxembourg, a small GDP also is accomplished by New Zealand to touch down on our ranking at No. 22. This island country is No. 53 in the globe with such a $205 billion GDP, but that is pulled up by its No. 10 ranking in SPI, which it owes to a full 100 score in water supply and sanitation, as well as increased standings in basic healthcare and individual rights. Balancing all this out is its $42,325 average income of No. 25-ranked.
