Our relationship with China, Russia (Soviet), and many other countries (where most atheists in the world lives) were not on the best terms during something called "The Cold War" which you might have heard about in movies at times. The bias was based on conflicting political and border issues. I'm pretty sure you won't find many Chinese, Soviet, Cuban, etc before the 80's.

Go back to your book and look at which country dominates Nobel prizes?
I'll save you the work: 43% US. (page 12, science category, 36% US overall)
Why? Because of socio-econo-political and historical issues, especially related to WWII.
Err... No. Soviets also were often awarded with the Nobel Prize. Let me mention some Soviet Nobel Prize Laureates:
Mikhail Sergeyevich Gorbachev, Peace, 1990
Iosif Aleksandrovich Brodsky, Literature, 1987
Pyotr Leonidovich Kapitsa, Physics, 1978
Menachem Begin*, born in now Belarus, Peace, 1978
Ilya Prigogine*, Chemistry, 1977
Andrei Dmitrievich Sakharov, Peace, 1975
Leonid Vitalyevich Kantorovich, Economics, 1975
Wassily Leontief, Economics, 1973
Aleksandr Solzhenitsyn, Literature, 1970
Michail Sholokhov, Literature, 1965
Nicolay G. Basov, Physics, 1964
Aleksandr M. Prokhorov, Physics, 1964
Lev Davidovich Landau, Physics, 1962
Boris Pasternak, Literature, 1958
Pavel Alekseyevich Cherenkov, Physics, 1958
Igor Yevgenyevich Tamm, Physics, 1958
Ilya Mikhailovich Frank, Physics, 1958
Nikolay Nikolayevich Semyonov, Chemistry, 1956
Ivan Bunin*, Literature, 1933
Secondly, socioeconomical problems is causing some countries to have poor educations leading to few scientists and research people. Many of these countries (like China for instance) was late to the capitalist game and simply didn't have the same base of educated scientists.
If atheist states failed in social issues, then what is the point of regarding religion as an antagonistic factor to social and scientific progress? It does not make any sense to me, since the religion - directly and indirectly - has fulfilled a major role in human progress. One way or another, religions have held the position of higher prominence within the human saga. And it would not be different in the Western civilisation.

One more thing. The statistics for current number of atheist v Christians in the world etc is ... to big surprise... the current numbers, i.e. as of now.
In America, the atheists are growing. More than 10% now, but they were barely 5% some 15-20 years ago. Keep that in mind too. And the same has been happening worldwide. The number of non-believers has increased the past 30 years or less. So again, the comparisons are not fair. Suddenly the increased number of non-believers in the past 20 years should be reflected on the past 100 years of Nobel prize statistics? (read the gallup report again, page 6, "TRENDS SINCE 2005: Religiosity drops by 9%, while atheism rises by 3%.". That's just 2005 to 2012 alone).
I believe that Atheism was once more popular, especially during Soviet times. In case you didn't know, Atheism is in full decline in China, Russia and even in Western Europe, where - under Pope Francis' papacy - people are not only limited to return to religion, but are even returning to attend churches, not to mention the Muslim immigration boom. I myself were an example of Atheist who vehemently condemned religion and now I have even found myself willing to attend churches sometimes. Take a look at the following statistics and form an opinion:
"Officially, the People's Republic of China is an atheist country but that is changing fast as many of its 1.3 billion citizens seek meaning and spiritual comfort that neither communism nor capitalism seem to have supplied.
Christian congregations in particular have skyrocketed since churches began reopening when Chairman Mao's death in 1976 signalled the end of the Cultural Revolution.
Less than four decades later, some believe China is now poised to become not just the world's number one economy but also its most numerous Christian nation.
"By my calculations China is destined to become the largest Christian country in the world very soon," said Fenggang Yang, a professor of sociology at Purdue University and author of Religion in China: Survival and Revival under Communist Rule.
"It is going to be less than a generation. Not many people are prepared for this dramatic change."
China's Protestant community, which had just one million members in 1949, has already overtaken those of countries more commonly associated with an evangelical boom. In 2010 there were more than 58 million Protestants in China compared to 40 million in Brazil and 36 million in South Africa, according to the Pew Research Centre's Forum on Religion and Public Life.

"(...) By 2030, China's total Christian population, including Catholics, would exceed 247 million, placing it above Mexico, Brazil and the United States as the largest Christian congregation in the world, he predicted.
"Mao thought he could eliminate religion. He thought he had accomplished this," Prof Yang said. "It's ironic – they didn't. They actually failed completely."

"Pope Francis is largely popular around the world, according to a study by Pew Research Center that includes information from 43 countries in all regions of the world.
He is most popular in Europe, where 84 percent of people view him favorably.
Pope Francis is also extremely popular in the U.S. and Latin America, where 78 percent and 72 percent, respectively, had favorable opinions of him. Fewer people in Africa, Asia and the Middle East have favorable opinions of him.

"(...)The Italian opinion poll Opinioni reported this week that more than four in five Italians have a 'positive' or 'extremely positive' opinion of the Pope.
Spain, which had been experiencing a decades-long slump, has also seen attendance figures begin to climb since the pontiff's appointment.
Catholic leaders in France, the USA and Latin America have also reported growth in the numbers of churchgoing Catholics.
