Incorrect. The Church is growing in the US.
In a 2015 survey by researchers at Georgetown University, Americans who self identify as Catholic, including those who do not attend Mass regularly, numbered 81.6 million or 25% of the population. 68.1 million or 20% of the American population are Catholics tied to a specific parish. About 25% of US Catholics say they attend Masses once a week or more, and about 38% went at least once a month. The study found that the number of US Catholics has increased by 3 to 6% each decade since 1965, and that the Catholic Church is "the most diverse in terms of race and ethnicity in the US," with Hispanics accounting for 38% of Catholics and blacks and Asians 3% each.
