The steel industry is now in decline when measured in terms of number of jobs provided, as is the mining. The reasons for the latter are mainly the high costs of production to extract the coal compared to other regions. Regional economic growth is below the broader Spanish rate, though in recent years growth in service industries has helped reduce Asturias's high rate of unemployment. Large out-of-town retail parks have opened near the region's largest cities (Gijón and Oviedo), whilst the ever-present Spanish construction industry appears to continue to thrive.
