The best and worst places to live.

• Position: GRAPH: INTERNATIONAL

One of the most revealing statistics you'll, find in this year's World Affairs issue is each nation's Human Development Index, or HDI. It measures the "livability" of a nation by combining several, pieces of data: life expectancy, education levels, and average income. HDI is measured on a scale of 0 to 1 (1 is the highest). The higher a nation's HDI value, the longer people there can expect to live, the longer they stay in school, and the wealthier they are likely to be.

ANALYZE THE GRAPH

(1) What is the difference in HDI values between the nation with the highest HDI and the nation with the lowest HDI?

a about .6

b about .7

c about .8

d about .9

(2) A majority of the 10 nations with the highest HDI values--

a have HDI values between .800 and .888

b have HDI values greater than .9

c are in Europe

d are in Africa

(3) Niger's HDI value is--the United States's HDI value.

a less than a third of

b less than a quarter of

c just over half of

d about two thirds of

(4) You can conclude from studying these two graphs that Algeria's and Kenya's HDI values (not shown) are both--.

a below .500

b above .775
