Passenger list statistics

Having completed the indexing of UK outbound passenger lists (1890 - 1960), ancestorsonboard have now compiled statistics on travellers to various countries in 5 year categories. Notice how the US (blue bars) is the most popular destination through almost the whole period, the huge number of travelers in the pre-WW1 period with Canada (red bars) taking an increasing share.

It would be nice if the company would provide a way that subscribers could develop this type of statistic from the database for themselves. At present the requirement to enter a surname precludes doing so.
