Evolution of the share of La Rochelle trade in relation to France as a whole

How were the data and visualization produced ?

Data for this chart was drawn from the Toflit18 database. Calculations of national flows were based on national records (sources: "Best Guess National partner") and flows from La Rochelle were based on local records (sources: "Best Guess region prod x part"). Free ports were excluded from the calculations.

How to read the visualization?

This chart shows the percentage of exports (in orange) and imports (in blue-green) of the La Rochelle customs region in relation to France's total exports and imports. Specific data can be seen by hovering over the bars for each year. The chart as a whole shows a gradual decline during the eighteenth century, despite an exceptional peak due to the expeditions under convoy in 1747.
