The 2016 Australian census which was conducted in August 2016 reports that Keith had a population of 1355 people of which 1076 lived in the town centre.

[2][3] A large granite outcrop outside the town called Mount Monster was a basis for the area's name until it was surveyed in 1884 and officially proclaimed Keith in 1889.

[12] In 1905 the general store was opened, and in 1907 the education department rented rooms out of the local institute to use as the school.

The 1910 church with contemporary lead light windows inspired by local history is a common tourist attraction.

Keith has a Mediterranean climate with mild, damp winters and warm to hot, dry summers.
