The U.S. Census Is Not Perfect: Thousands Of Americans Probably Go Uncounted GMAT Critical Reasoning

Question:The U.S. census is not perfect: thousands of Americans probably go uncounted. However, the basic statistical portrait of the nation painted by the census is accurate. Certainly some of the poor go uncounted, particularly the homeless; but some of the rich go uncounted as well, because they are often abroad or traveling between one residence and another.

Which of the following is an assumption on which the argument above depends?

(A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census.
(B) All Americans may reasonably be classified as either poor or rich.
(C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted.
(D) The number of homeless Americans is approximately equal to the number of rich Americans.
(E) The primary purpose of the census is to analyze the economic status of the American population.

Answer: C
Explanation
:

Given that The U.S. census isn't perfect; possibly thousands of people are missed. But the general statistical picture of the country that the census paints is correct. Some of the poor don't get counted, especially the homeless. But some of the rich don't get counted either, because they are often out of the country or moving from one place to another.

Let's approach the answer choices.

A: Incorrect
Nobody cares why people don't fill out the census; what matters is how many of them do.

B: Incorrect
This goes along with my second guess, but the wording is too strong. We don't need all Americans to be poor or rich for the argument to work, because even if there were some Americans who couldn't be put into either category, the argument would still work. It would get a little confusing (what about those people in the middle class? ), but we wouldn't have solid proof that the census was bad.

C: Correct
This is related to my initial assumption and difficult to figure out, so breaking down the arithmetic helps. Imagine there are 100 persons in the country but only 80 count. If 50 poor, 50 rich is reality and 50 poor and 30 rich are counted, we'd have missed 66% of the rich and 0% of the poor, and our count doesn't accurately reflect America's breakdown. Even if we miss 10 poor and 10 rich (the same percentage of 50), our country's statistics are still accurate (40 and 40 out of 80, versus 50 and 50 out of 100).

D: Incorrect
It makes no difference in this context how many actual persons there are in each category. We are solely interested in the breakdown of the percentages.

E: Incorrect
The only thing that matters are the census's statistical results; its goal is irrelevant.
