 Bahrain has benefited from the oil boom since 2001, with economic growth of 5.5%.It has succeeded in attracting investment from other Persian Gulf states partly because it used the revenues of the 1970s-early 80s boom to invest in infrastructure development and other projects to improve the standard of living; health, education, housing, electricity, water, and roads all received attention.The success of ventures such as the Bahrain Grand Prix has raised the Kingdom's international profile, and combined with the boom in Islamic banking, has encouraged major airlines to resume services to the country, with Lufthansa announcing on 14 March 2006 that it would schedule three flights a week to Muharraq from Frankfurt.
