British sugar production shifted decisively from old to new colonies between 1813 and 1833

Evidence

Between 1813 and 1833 Jamaica’s production declined by nearly one-sixth; the exports of Antigua, Nevis and Tobago by more than one-quarter, St. Kitts by nearly one-half, St. Lucia’s by two-thirds, St. Vincent’s by one-sixth, Grenada’s by almost one-eighth. Dominica’s exports showed a slight increase, while Barbados almost doubled in its exports. On the other hand, the output of the newer colonies increased, British Guiana’s by two and a half times, Trinidad’s by one-third. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 776
