In 2002, the MetLife Mature Market Institute first pioneered the collection of national market survey data on nursing home, assisted living, and home care costs. Since then, these market survey data have been updated and released on an annual basis. In 2007, cost information on adult day services was included for the first time. This market survey, conducted in conjunction with LifePlans, Inc., contains daily private-pay rates for private and semi-private rooms in licensed nursing homes, monthly base rates for assisted living communities, hourly rates for home health aides from licensed agencies and agency-provided homemaker companion services, and daily rates for adult day services across the United States (abstract from: p. 4 of report).
