Hours volunteered is a pretty deceptive stat. Volunteering is a pretty middle class soccer mom activity and when you're working 50-60 hours in a developing country just to survive, volunteering isn't all that possible. Added to the fact that a lot American volunteer is based around the church or for political causes, it's makes it less altruistic than one might assume.
That said civil society in the west is a lot more developed than in China, though China has seem a boom in non-profits and NGOs.
LOL- there is not a single sentence in your reply above ( well maybe one) that is based on facts. In fact it’s safe to say you rushed in to reply in defense of the motherland instead of educating yourself about this American exceptionalism
When provided stats , you start off with the " oh we can't beleive in those stats "
because it does not suit your meme.
Generation X shows a high rate of volunteering in 2010 after increases since their teen years
 Generation X stepped up their commitment in 2010, giving 2.3 billion hours of service—an increase of almost 110 million hours since 2009. Once stereotyped as skeptical and disengaged, Generation X is showing signs of optimism that they can make a difference in their communities through service as they become more connected to local networks through their careers and their children.
 Gen X members have more than doubled their volunteer rate between 1989 and the present day (2010). In 1989, 12.3 percent of Generation X members who were between 16 (the minimum age to participate in the survey) and 24 volunteered with an organization. By 2010, the Gen X volunteer rate had risen to 29.2 percent.
 The increases in volunteer rates seen among Generation X reflect an observable pattern in volunteering among different age groups that holds true year after year. You might call it a “volunteer lifecycle.” What we see is that in every year for which we have volunteer data the following is true:
o
The volunteer rate tends to be higher in teen years than in early adulthood, when the volunteering rate is typically at its second lowest point after very old age.
o In the mid- to late twenties, volunteering rates begin to pick up again, growing until they reach a peak around the time of middle age.
o After middle age, volunteering rates begin to drop as age increases.
Volunteers served 8.1 billion hours in 2010, valued at an estimated $173 billion.
