'N/A' indicates that we don't have data for this name in that country or time (usually because it's quite uncommon there and our stats don't go down that far). It doesn't mean that there's no-one there with that name at all!

For less common surnames, the figures get progressively less reliable the fewer holders of that name there are. This data is aggregated from several public lists, and some stats are interpolated from known values. The margin of error is well over 100% at the rarest end of the table!

It's possible for a surname to gain in rank while being less common per million people (or vice versa) as there are now more surnames in the UK as a result of immigration. In mathematical terms, the tail has got longer, with a far larger number of less common surnames.
