What the code means
A marriage and family therapist is a person with a master's degree in marriage and family therapy, or a master's or doctoral degree in a related mental health field with substantially equivalent coursework in marriage and family therapy, who receives supervised clinical experience, or a person who meets the state requirements to practice as a marriage and family therapist. A marriage and family therapist treats mental and emotional disorders within the context of marriage and family systems. A marriage and family therapist provides mental health and counseling services to individuals, couples, families, and groups.

Who registers under this code
100,510 of these are people and 9,411 are organisations, so 9% of the code is businesses rather than clinicians. Half of them had registered by 2016, and 31,647 registered in the last five years, 29% of the current population.
That is close to the pace of the registry as a whole.
Where the practices are
By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider
These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
