Domestically, the political agenda was increasingly liberal, with a number of shifts in the direction of gradual political reform, social reform, and the widening of the franchise. There were unprecedented demographic changes: the population of England and Wales almost doubled from 16.8 million in 1851 to 30.5 million in 1901, and Scotland's population also rose rapidly, from 2.8 million in 1851 to 4.4 million in 1901. However, Ireland's population decreased sharply, from 8.2 million in 1841 to less than 4.5 million in 1901, mostly due to emigration and the Great Famine. Between 1837 and 1901 about 15 million emigrated from Great Britain, mostly to the United States, Canada, South Africa, New Zealand, and Australia. Thanks to educational reforms, the British population not only approached universal literacy towards the end of the era but also became increasingly well-educated; the market for reading materials of all kinds boomed.
