Based on the following factors, what do developing countries have in common?
The following factors are population, median age, growth rate, birth rate, death rate, migration rate, infant mortality, life expectancy, fertility rate, literacy rate, and GDP?
Keeping in mind that not every developing country will have all of these factors...
In general, there's no way to really connect population to whether or not a country is "developing." You can have very small countries (Gabon -- 1.5 million) and big countries (Philippines -- 97 million) both of which would be considered developing.
Outside of that, though, there are commonalities:
Developing countries tend to have high growth rate, birth rate, death rate, migration rate, infant mortality, fertility rate.
They have low median age, life expectancy, literacy and GDP.
The common features of developing countries in term of listed factors are discussed below
Population: there need not be any commonality between developing countries in term of population the two countries with the largest population - that is China and India are developing countries. At the same time small countries like Bangladesh and Sri Lanka are also developing countries.
Median age, birth rate, death rate, infant mortality, life expectancy, and fertility rate: All these factors have direct bearing on the population growth rate. And the population growth rate including birth rate and death rate are known to be related to the stage of economic development stage of a country. Thus developing countries are more likely to have a combination of low death rate with falling birth rate. This would mean high but declining population growth rate.
Growth rate and GDP: These factors really define the countries as developed, developing or under developed. Developing countries have low to medium GDP which is growing at medium to high rate.
Migration rate: Economic development is always marked by shift from agriculture based economy to industry based economy. This in turn involves migration of people from rural to urban areas. Therefore developing countries are likely to experience high migration rate.
Literacy rate: Economic development, among other things results in higher literacy. Therefore developing countries are likely to have low to medium literacy rates, which is increasing at medium to high rates.
