Before the 1977 national municipal reform, Nuevitas was divided into the barrios of Primero, Segundo, Tercero, Alvaro Reinoso, Lugareño, Redención, San Miguel and Senado.

[4] Nuevitas is not a very large city but it is one of Cuba's most important towns because of its commercial and industrial activities.

Nuevitas is sheltered by a huge harbor, has two auxiliary ports, and is a major shipping point for Cuban sugar as well as other products from the surrounding agricultural region.

The principal road crossing the municipality is the state highway "Circuito Norte" (CN).

The railway station is the terminus of two lines: one from Camagüey, and a second from Santa Clara, through the Atlantic Coast and Morón.
