suggestions for ERD

I am trying to prepare an ERD. There are three entities population, GeographicRegion, and inidividuals.

looking for some suggestions for attributes for them?

Some I have: Individuals: race, gender, name

Population: size, race

GeographicRegions: region, temp

any other suggestions?

From stackoverflow

• The information you provide is very vague for definite suggestions, however, here are some sample attributes assuming your context is demography related :

  Individual - Education, Ethnic category, native language/dialect, Religion, Age, Number of Offspring

  Population - Average life expectancy (this may turn out to be a calculated field), Birth rate, death rates, etc.

  Geographic Region - Climate

  Can't think of any more right now... ;-)

• For your homework assignment, you might find some useful information at the HIS Registry of Peoples

  This site documents the Registry of Peoples (ROP) for the Harvest Information System (HIS). This registry defines the standardized codes used for identifying the peoples of the world.

  Lots of entities and attributes your perusal.
