In 1832 it was calculated that the whole number of persons deriving subsistence on the Ohio, including the crews of steam- and flat-boats, mechanics and laborers employed in building and repairing boats, woodcutters, and persons employed in furnishing, supplying, loading and unloading these boats, was ninety thousand. At this time, 1832, the boats numbered four hundred and fifty and their burden ninety thousand tons. In 1843 the whole number of steamboats constructed at Cincinnati alone was forty-five; the aggregate amount of their tonnage was twelve thousand and thirty-five tons, and their cost $705,000. This gives an average of two hundred and sixty-seven tons for each boat and about $16,000 for the cost of each.
The models of these 1843 boats, as well as their finish and accommodations, evinced a progressive improvement upon earlier boats. They had more length and less draught, and were faster than those of the last generation, while the hulls were more staunch, though they contained less weight of timber. The cabins were not so gaudy and expensive as those of former years but were greatly superior in comfort and convenience.
In 1844 the number of steamboats employed in navigating the Mississippi and its tributaries was four hundred and fifty. The average burden of these boats was 200 tons each, making an aggregate of 90,000 tons and their aggregate value, at $80 per ton, was $7,200,000. Many of these were fine vessels, affording most comfortable accommodations for passengers, and compared favorably in all particulars with the best packets in any part of the world. The number of persons engaged in navigating the steam-boats at this time varied from twenty-five to fifty for each boat, or an average of about thirty-five persons, which gives a total of 15,750 persons employed.
It appears from the reports of the Louisville and Portland Canal at this time that more than seven hundred flat-boats passed that canal in one year. There were, therefore, probably four thousand descending the Mississippi, and counting five men to a boat there were 20,000 persons employed in flat-boating. The cost of these boats was in the neighborhood of $400,000, which, as they did not return, was an annual expense; the cost of loading, navigating, and unloading them approximated $900,000, making a total annual expenditure upon this class of boats $1,300,000.
If, in 1834, the number of steamboats on western waters was two hundred and thirty, and they carried 39,000 tons, the expense of running them could be estimated as follows:[71]
| 60 boats, over 200 tons, 108 running days, at $140. per day— | $1,512,000. |
| 70 boats, 120-200 tons, 240 running days, at $90. per day— | 1,512,000. |
| 100 boats, under 120 tons, 270 running days, at $60. per day— | 1,620,000. |

| Total yearly expenses | $4,645,000. |
In 1844 the calculation was:
This sum, reduced to the different items producing it, would be apportioned as follows:
| For wages, 36% | $3,252,960. |
| For wood, 30% | 2,710,800. |
| For provisions, 18% | 1,626,480. |
| For contingencies, 16% | 1,445,760. |
