Naming habits have changed over time, especially in recent decades. In the past in the UK, given names were chosen from a much smaller range than today. In the late 18th century, for example, well over 20% of girls were called Mary. The top three most popular names accounted for around 50% of the population, for both boys and girls. Gradually the range of names widened, and by the 1960s the top name was given to only about 10% of girls (Susan) and 5% of boys (Paul). Most of the popular names had some associations with the Christian Bible, for example Mary and Elizabeth for girls, John and James for boys. As late as the 1960s the given name was known as the 'Christian name'. For example official forms asked for a person's Christian name. The term 'given name' began to be used in the 1970s and 80s, reflecting the fact that an increasing proportion of the population was no longer Christian. Today some names are still much more popular than others, for example Olivia and Lily for girls, Harry and Oliver for boys. However names are now heavily influenced by fashion, therefore popularity changes much more quickly than in the past. The range is also wider, with the top names accounting for only a few percent. These days some parents 'make up' completely new names for their babies. However, the vast majority still chose from a range of conventional names.
