Giving Statistics

The charitable donation continued to increase in 2017, and the estimated charity amount was 41,202 million dollars. For the third consecutive year, the total donation reached a record level. The overall size of this growth and charitable donation shows the essential role of charity organizations in our society, an even bigger role.

In 2017, the charity donated a total of $ 402 billion (2.1% of GDP). Since 2016, the inflation-adjusted dollar increased by 2%, increased by 0%.

Since 1977, except for three years, annual cash increase has increased: 1987, 2008 and 2009

Changes in total annual contribution amount between 1977 and 2017 increased by 8.94 billion dollars (current US dollar), and the current total dollar supply fluctuation between 2016 and 2017 is 40 years average It is getting much bigger.

Over the 40 years from 1977 to 2017, the total contribution rate reached or exceeded 0% of GDP. In most of the 1970's, 80's and 90's, it was less than 0%. In the majority of 2000, the percentage of total donations to GDP rose more than 0%, but declined to 9% between 2009 and 2011. In the five years of 2013, the total donation for GDP over the four years was from 1% to 2017.

As before, most of the donation is an individual donation. Specifically, individual contributions amounted to 286.65 billion dollars, accounting for 70% of all donations, a 0% increase compared to 2016.

The Foundation provided $ 66.9 billion (16% of all donations), including subsidies from the Independent Foundation, the Community Social Foundation and the Operating Foundation. This is 6% more than last year.

Historically, personal donations accounted for more than two-thirds of all donations. If you add a gift from your property, that category accounts for nearly 80% of all contributions. In other words, rather than a large foundation or company, donated citizens are in charge of most of the annual donation.

Environment / animal focused charity increased by 2% to 11.83 billion dollars (3% of total donation)

Historically, religious organizations have the largest share of charitable donation. This still holds in 2016. This year's donation increased by 9%, 31% of the total donation, or 127.37 billion dollars, was spent on religious organizations. Most of this donation comes from people donating to the local worship place.

Scientists often want to connect with the public by talking about how their research affects broad concern. But they are accustomed to talking about these effects in an abstract way, such as providing statistics on the population. Statistics are important, but if real people are written as letters in stories, they will pay more attention and make the reader more memorable. When scientists constantly make statistics but they do not talk about how they relate to people's lives, they risk the cold and distant dangers. Anecdotes may not have scientific writing status, but they are absolutely necessary for news and literary nonfiction.

Statistical data rarely gives a simple yes / no answer to analytical problems. Interpretation usually comes from the level of statistical significance applied to numerical values ​​and usually means the probability that a value precisely rejects the null hypothesis (sometimes called p value). The standard approach is to test the null hypothesis about the alternative hypothesis. An important area is a set of values ​​of estimators that refuse the null hypothesis. Therefore, assuming that the null hypothesis is true (statistical significance), the probability of type I error is the probability that the estimator belongs to the critical region and the probability of type II error is the probability that the estimate is in a specific critical region It is probability not to belong. . The statistical power of the test is the probability of correctly rejecting the null hypothesis when the null hypothesis is false.
