The following table shows an importation into the district of Havana alone, for a period of 31 years, of 225,574 Africans:
| 1790 | 2,534 | 1806 | 4,395 |
| 1791 | 8,498 | 1807 | 2,565 |
| 1792 | 8,528 | 1808 | 1,607 |
| 1793 | 3,777 | 1809 | 1,152 |
| 1794 | 4,164 | 1810 | 6,672 |
| 1795 | 5,832 | 1811 | 6,349 |

| 1805 | 4,999 | ||
| Total | 225,574 |
But Havana was not the only port through which slaves entered Cuba, and the recognized channels were not the only ones through which they came. Therefore, to provide for the illicit importations and those made at Trinidad and Santiago these figures should be increased by at least one fourth to cover the importations for the whole island. This gives us the following results:
| From | 1521 to 1763 | 60,000 | |
| 1764 | 33,409 | ||
| Havana | |||
| From | 1791 to 1805 | 91,211 | |
| 1806 to 1820 | 131,829 | ||
| Secret trade and trade in other parts of the island | 56,000 | ||
| 372,499 | |||
As we have seen, the trade did not stop when it was made illegal. We have the authority of one of the British commissioners at Havana that in 1821 twenty-six vessels engaged in the slave trade landed 6,415 slaves; and this gentleman also states that only about fifty per cent. of such arrivals ever reached the attention of the commissioners, so that to this number an equal amount should be added to provide for the slaves imported by "underground" methods.
The yearly reports of these British commissioners furnish some food for thought on this subject. They report the following data:
| 1822, 10 vessels arrived, bringing—estimated—3,000 | slaves | |
| 1823, 4 vessels arrived, bringing—estimated—1,200 | " | |
| 1824, 17 vessels arrived, bringing—estimated—5,100 | " | |
| 1825, 14 vessels arrived, bringing—estimated—4,200 | " | |
| 1826, 11 vessels arrived, bringing—estimated—3,000 | " | |
| 1827, 10 vessels arrived, bringing—estimated—3,500 | " | |
| 1828, 28 vessels arrived, bringing—estimated—7,000 | " | |
| 27,000 | " | |
| Adding the estimated one half for the number not reported | 13,500 | " |
| 40,500 | " |
In 1838, the British consul at Havana reported to the foreign office in London, regarding slave importations into Cuba for the previous nine years:
| 1829 | 8,600 |
| 1830 | 9,800 |
| 1831 | 10,400 |
| 1832 | 8,200 |
| 1833 | 9,000 |
| 1834 | 11,400 |
| 1835 | 14,800 |
| 1836 | 14,200 |
| 1837 | 15,200 |
| Total | 101,600 |
| Add 1/5 | 20,320 |
| 121,920 |
It will be observed that the consulate adds only one fifth to cover the secret importations during this period.
