Counting people

Counting people obviously helps to understand the different races and ethnicities when talking about science and statistics. It also allows scientists to quantify people by their races over many places in the world.

      From a sociological point of view, counting people according to racial categories is kind of necessary because it's supposed to be good to have knowledge about where people com from, who they are, human race and their behavior. However, this is only useful up to certain point. Usually some people would consider this as racism and might perceive it as an exaggerated defense  of a particular group.

     Talking about the conditions of the people in society, this shouldn't affect or influence their conditions if it;s done only for a statistic study of the census. It is acceptable to separate people into different race/ethnic groups as long as that doesn't affect some peoples' conditions but they are necessary for the society so they can keep track of everything and have knowledge about important facts on each society.
