(JTA) — There may be no such thing as a free lunch. But there is a free 10-day trip to Israel.

For 16 years now, the Birthright Israel Foundation has been giving away guided tours of the country to young people from around the world. The goal is to strengthen participants’ Jewish identity and connection to Israel. Tens of thousands of 18-26 year-olds sign up every year to see the highlights with a group of peers.

Someone is paying for all those trips. But who?

Inside Philanthropy, a website that investigates charities, delves into the program’s funding in an article published Tuesday.

Here are some notable numbers from Inside Philanthropy and the Birthright Israel website. Birthright contested some of the numbers in the original Inside Philanthropy article and those changes are reflected below.

$3,000 – Average price of the trip, per person

$47 million – Birthright’s budget in 2015

45,000 – Total participants in 2015

$40 million – Annual contribution by the Israeli government

$50 million – Annual contribution by the organized international Jewish community, including individual donors and Jewish family foundations

30,000 – Number of non-governmental donors (individuals, foundations and institutions) who give to the program each year

$2.5 million – Top annual individual donation

7 – Number of Jewish family foundations who have contributed a million dollars or more in recent years

$200 million – Amount billionaire casino mogul Sheldon Adelson and his wife, Miriam Adelson, have donated since 2009, making them the biggest funders in the program’s history

$2.7 million – Amount raised last year by “direct marketing” initiatives

Over 500,000 – Total number of trip alumni

80,000 – Number of Israelis who have participated in the program

1999 – Year the program was founded

66 – Number of countries represented by participants

This is a moment of great uncertainty for the news media, for the Jewish people, and for our sacred democracy. It is a time of confusion and declining trust in public institutions.

With no paywall or subscriptions, the Forward is entirely supported by readers like you. Every dollar you give this Passover is invested in the future of the Forward — and telling the American Jewish story fully and fairly.

The Forward doesn’t rely on funding from institutions like governments or your local Jewish federation. There are thousands of readers like you who give us $18 or $36 or $100 each month or year.

Don't just read the Forward - invest in it. Make a matched gift today.

Support our mission to tell the Jewish story fully and fairly.
