About 4 out of 10 (27%) of Americans say they live with a disability that interferes with their daily lives, according to a survey conducted by the Pew Research Center. The survey was conducted last fall by telephone and focused on activities like using the Web and daily errands. While 8 out of 10 (81%) who said they had no disabilities also said they used the Internet. But just over half (54%) of those who said they were living with a disability also said they used the Internet.
