I'm going to try to find the article when I get home, but I read recently that Italy's birth rate among ethnic Italians is actually negative, but that their overall population is increasing at 2-3% per year and that by the year 2020 Italy would be a majority muslim nation unless the trends were reversed.
That tidbit of information was in an article about the grossly intrusive new mosque built in Rome, the one that the Pope had opposed building and had personally asked Rome's muslim leaders not to build.
