Billings is also the largest retail destination for much of the same area.
The city is experiencing rapid growth and a strong economy; it has had and is continuing to have the largest growth of any city in Montana. Parts of the metro area are seeing hyper growth. From 2000 to 2010 Lockwood, an eastern suburb, saw growth of 57.8%, the largest growth rate of any community in Montana.
