Sustainable development is a pattern of using the resources so that they will be there for future generations, such as preserving the environment.
Economic Growth is an increase of activity of the economy, such as an increase in GDP.
Economic Development is an increase of the quality of life of individuals in a certain area.
HDI, having to do with Economic Development, stands for Human Development Index, and it measures the quality of life. To measure the quality of life, it uses data such as life expectancy at birth, GDP per capital, and literacy rate. Pakistan has an HDI of .551 which puts them very low on the ranking.
HDI is supposed to measure the quality of life for people in a given area. Though it sounds a good idea, it is lacking some major points. Such as the amount of actual happiness people are experiencing while they are alive, because the HDI measures how long people live and how smart they are when they are living. This is a good idea, but I do think the actual scale needs improvement.
