Europe has changed dramatically over the past century. One major change is that European countries now mainly belong to the European Union and have a single currency, the Euro rather than individual currencies such as the French franc, the Greek drachma, and the German mark, which they possessed in the twentieth century.
European religion has changed from primarily Christian to primarily secular, albeit with a rise in Islam especially among immigrants. Along with this, gender roles have changed, with women no longer relegated to domesticity but equal to men in every aspect of life. Family size has also decreased dramatically and life expectancy increased.
Technological change has affected every aspect of society, including food, communications, transportation, clothing, and entertainment. A far smaller number of people are involved in food production and food supply chains have become global rather than local. Fast food has become increasingly common, and clothing and furniture are now mass produced rather than hand-crafted for the most part. The telephone and internet have made communications instantaneous and transportation has shifted from horses and trains to a combination of trains, cars, and buses.
