The education rate for Great Britain seems starkly low.

[quote=The Royal Commission on the state of popular education in England, 1861]
The whole population of England and Wales, as estimated by the Registrar-General in the summer of 1858, amounted to 19,523,103. The number of children whose names ought, at the same date, to have been on the school books, in order that all might receive some education, was 2,655,767. The number we found to be actually on the books was 2,535,462, thus leaving 120,305 children without any school instruction whatever. The proportion, therefore, of scholars in week-day schools of all kinds to the entire population was 1 in 7.7 or 12.99 per cent. Of these 321,768 are estimated to have been above the condition of such as are commonly comprehended in the expression 'poorer classes', and hence are beyond the range of our present inquiry. Deducting these from the whole number of children on the books of some school, we find that 2,213,694 children belonging to the poorer classes were, when our statistics were collected and compiled, receiving elementary instruction in day schools. [b]Looking, therefore, at mere numbers as indicating the state of popular education in England and Wales, the proportion of children receiving instruction to the whole population is, in our opinion, nearly as high as can be reasonably expected. In Prussia, where it is compulsory, 1 in 6.27; in England and Wales it is, as we have seen, 1 in 7.7; in Holland it is 1 in 8.11; in France it is 1 in 9.0.[/b] [/quote]

Ireland could be expected to be lower than that, but more populous Scotland would be higher. For ease of comparison to the stats;

Great Britain: 62%
Prussia: 85%
Netherlands: 80% (+9% soon).

And that, of course, isn't factoring into account that the United Kingdom was /the/ home of higher education in the time period.
