The National Association of Home Builders (NAHB) redesigned its Multifamily Market Survey (MMS) in the first quarter of 2023 to make it easier to interpret and more similar to the NAHB/Wells Fargo Housing Market Index for single-family housing. The MMS produces two separate indices. The Multifamily Production Index (MPI) had a reading of 50 for the first quarter while the Multifamily Occupancy Index (MOI) reading was 82. Readings above 50 are considered good.
