The population of Scotland has been steadily increasing over the past few decades. In 1991, the population was estimated to be 5.1 million. By 2011, the population had grown to 5.3 million.
The growth in the population of Scotland is primarily due to net migration. In recent years, there have been more people moving to Scotland than there have been people moving away from Scotland.
The population of Scotland is also aging. The proportion of the population aged 65 and over has been increasing, while the proportion of the population aged under 16 has been decreasing.
