There were a wide variety of religious beliefs in the United States in the 1980s, as there are today. The largest single group are those who self-identify as "Christians", constituting approximately two thirds of the population, although that designation can range from people whose families were Christian who themselves are not actively involved in religious life to those who are extremely devout. Roman Catholics are an increasing proportion of the Christian population; Roman Catholicism is the major denomination of the Hispanic population in the United States. Evangelical churches are growing in size among other U.S. population, while the mainline Protestant churches (Episcopalian, Lutheran, Presbyterian, Methodist) are gradually declining in membership. Judaism and Islam have well established traditions in the U.S., and other belief traditions, including atheism, Buddhism, Hinduism, and Native American religions occur in specific populations.
