Lithuania
The $53.3 billion GDP of this European nation currently ranked only No. 86 in the world, as well as its average income of $26,429 is lesser at No. 50 in the world. However, its No. 31 standings in SPI provides it a raise. In the SPI, connectivity to adequate medical care, access to water and sanitation, and individual rights are highly rated in Lithuania. Like so many Euro countries, access to academic education is low at 49.79 points, but health and wellness, as well as inclusiveness, are also low at 67.84 and 63.54 points.

Saudi Arabia
As the world’s biggest producer of oil, without Saudi Arabia, no compilation of the richest nations would’ve been comprehensive. Nearly half of Saudi Arabia’s $782.4 billion GDP, ranked No. 18, tends to come from oil, as per OPEC. Saudi Arabia ought to be higher than No. 38 with such a high of a GDP ranking. However, its No. 61 ranked average income of $21,540, and the No. 86 SPI ranking nearly pulled it off of the ranking completely. The SPI of Saudi Arabia receives raises from convenient access to water and sanitation and proper healthcare. However, with three extremely poor results, it takes tremendous hits: 13.87 inclusiveness points, 17.26 personal rights points, and 36.82 access points to academic education.
