"La familia va a muchos conciertos."
Translation:The family goes to many concerts.
go vs goes - American English uses the singular but British English can use either singular or plural.
In proper English - as opposed to American - the family go to a lot of concerts is perfectly correct
La familia is a singular collective noun and uses the 3rd person singular verb: la familia va.
Las familias would be plural and would use the 3rd person plural verb: las familias van.
Mi familia es de Bolivia.
Nuestras familias son de Puerto Rico.
