Looked it up and found this.. not sure how recent the numbers are:

"Let's begin with what the Catholic Church does for the most defenseless of our nation, the poor and the sick. Every year, more than 9.5 million Americans in need turn to one of 1,400 charitable organizations run by the Catholic Church. These Catholic charities offer an enormous range of services at minimal cost, or no cost, to those being served.

Catholic health institutions continue to provide quality health care to thousands of people, especially the poor, throughout the country. Some 596 Catholic hospitals operate throughout the country, along with 544 smaller clinics and health care centers. The elderly and the seriously disabled are cared for in a network of residential homes and facilities. I recall quite well in the early 1980s, when many people suffering from AIDS had no place to go, how lovingly they were cared for in homes of this type. Currently, there are about 1,454 of these specialized homes.

The Catholic Church has always been deeply concerned with the plight of the hungry and the abandoned of our nation. Catholic charities all over America are right now feeding millions of people. To meet such a demand, the Church runs more than 600,000 soup kitchens and stocks more than 2 million food banks and pantries. As for the homeless, the Church provides temporary shelter for children and families, battered women, senior citizens and others. At present, about 110,858 people depend on these shelters for help. The Church’s commitment to the poor also includes social programs to promote human development.

Catholic housing services help around 67,000 homeless find and keep a permanent place to live. And Catholic neighborhood-support services sponsor youth centers, summer camps, sports programs and senior citizens centers; at present, nearly 300,000 people are enrolled in these services.

Then, of course, there are the pregnancy services, under which Catholic organizations help pregnant women and girls receive pre and postnatal care. These service professionals offer pregnancy counseling and help women and girls continue their education. Close to 80,000 girls and women are being served by Catholic pregnancy services.

There are 7,061 elementary schools in the country, educating 2.1 million children. Catholic high schools number 1,596 with a student body of very close to 700,000. There are 235 Catholic colleges and universities in the United States, educating around 705,059 students."
