In order to better understand how the Human Development Index translates into real life, we should consider that a child that is born in 2014 in Norway has a life expectancy of about years compared with a life expectancy of about for a child born in the same year in the Democratic Republic of the Congo.

82.10 (2014) ; 58.83 (2014).

Explanation:

Life expectancy can simply be explained as the average time in which someone can live at a particular location or geological zone. For instance, the life expectancy for a person living in the United States of America is about 78.8 and for a person in Nigeria is about 53.95 years(as of 2017) for a child born in the same year.

The Human Development Index (HDI) is the statistical representation of GNI per capita and life expectancy. It is also use to represent the geometric mean of education of a country.

The life expectancy of Norway in 2014 and that of Democratic Republic of the Congo is 82.10 (2014) ; 58.83 (2014) respectively.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
