The Pew Research Center is an honest organization that provides often interesting and useful data on social issues, public opinion and demographic trends. That assertion, though, needs to be qualified by pointing out that Pew is honest by way of commission, while it is often less so by way of omission. The center regularly conducts a survey entitled "News IQ" in which American adults are surveyed on their knowledge of current events.
If I recall correctly, Pew originally included racial breakdowns in the quiz results, though it stopped doing so several years ago and it looks as though Pew only maintains the most recent results on its site. Now it appears as though a stop to breaking down results by sex is imminent. Report results from the latest survey only separate out male and female responses for three questions that specifically have to do with women (tragically, men performed better on all three!). However, after completing the quiz online, results are broken down by sex, age, and educational attainment.
While men performed better on the three ostensibly girl power questions (identifying Marissa Mayer, the percentage of congress critters who are female, and female college graduation rates), women actually outscored men on two of the thirteen items, the two concerning subjects of elevated interest to many women--same-sex marriage and educational curricula. While sexless feminists might be interested in female figures engaged in traditionally masculine pursuits, most women are far more interested in traditionally (and biologically) feminine concerns like social inclusion and nurturing.
If Pew stops reporting results by sex, we're left with age (fairly predictable question by question and a dead giveaway overall), education (more obvious than the outcome of a Globetrotters-Generals game), and party affiliation (almost indistinguishable this time around).
One age-related result does catch the eye:
Percentages who correctly answered "Nigeria" by age range:
18-29 -- 47%
30-49 -- 45%
50-64 -- 43%
65+ -- 29%
The question is multiple choice with four possible answers, so old fogies are essentially oblivious to the specific differences in rates of fertility between various different countries in the world. You don't have to care about demographics for demographics to care about you, of course.
