Spain’s population growth has experienced significant fluctuations over the past century. After a steady increase during much of the 20th century, growth slowed considerably at the turn of the 21st century due to declining birth rates and an aging population. However, Spain saw a notable population boost in the early 2000s, primarily driven by immigration from Latin America, Eastern Europe, and North Africa. In recent years, natural growth has stagnated, with deaths outnumbering births, but the overall population has continued to rise slowly, reaching approximately 48 million in 2023, mainly due to continued immigration. This demographic trend presents challenges for Spain, including a shrinking workforce and increased pressure on social services to support an older population.
