Why do the countries of British Isle have a larger population than Scandinavian Peninsula?

This statement is not accurate. The Scandinavian Peninsula, which includes the countries of Norway, Sweden, and Finland, has a combined population of approximately 21.9 million people. On the other hand, the British Isles, which include the countries of the United Kingdom (England, Scotland, Wales, and Northern Ireland) and the Republic of Ireland, have a combined population of approximately 72.5 million people. Therefore, the British Isles have a significantly larger population compared to the Scandinavian Peninsula.
