Before the lock and dam system was built on the Kentucky River, Gratz was one of the most prosperous towns in the area due to the business of portaging goods around an unnavigable part of the river (Lock #2 is just up river at Lockport). Goods were also ferried across the river and transported up KY 22 to Pleasureville, which had a railroad depot.
The town's streets are laid out in a grid pattern. There is a local bank, and many large, well-built houses.
Before public electric service was available, a diesel powered generator fed street lights (and some homes?) from dusk until about 10pm. A former operator of this plant reported that he learned how much fuel to put into the engine so that it would run out at the desired time (saved him a trip down the hill).
There were 35 households out of which 28.6% had children under the age of 18 living with them, 60.0% were married couples living together, 2.9% had a female householder with no husband present, and 31.4% were non-families. 28.6% of all households were made up of individuals and 5.7% had someone living alone who was 65 years of age or older. The average household size was 2.54 and the average family size was 3.17.

The median age was 33 years. For every 100 females there were 154.3 males. For every 100 females age 18 and over, there were 123.3 males.
The median income for a household in the city was $14,167, and the median income for a family was $23,750. Males had a median income of $16,250 versus $20,750 for females. The per capita income for the city was $9,217. There were 12.5% of families and 28.0% of the population living below the poverty line, including 40.0% of under eighteens and none of those over 64.
