Countries or states are typically ranked on the HDI scale from:

0 to 10
0 to 100
0 to 1
-1 to 1

The correct answer is: b) 0 to 100

The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher if it performs better on these indicators.

The HDI was developed by the United Nations Development Programme (UNDP) and is published annually as part of the Human Development Report. The HDI is used to rank countries from 0 to 100, with 100 being the highest possible score.

The HDI is a useful tool for comparing the level of human development in different countries. It can also be used to track progress over time. However, the HDI has been criticized for being too simplistic and for not taking into account other important factors, such as gender equality and environmental sustainability.

Here is a brief explanation of each option:

  • a) 0 to 10: This option is incorrect because the HDI is ranked from 0 to 100, not 0 to 10.
  • b) 0 to 100: This option is correct because the HDI is ranked from 0 to 100.
  • c) 0 to 1: This option is incorrect because the HDI is ranked from 0 to 100, not 0 to 1.
  • d) -1 to 1: This option is incorrect because the HDI is ranked from 0 to 100, not -1 to 1.
