I write for Acoustic Magazine, and I can confirm Chris's link - loads of schools are replacing recorders with ukuleles because they are more popular, and children prefer learning them.
I attend the Acoustic Festival Of Great Britain every year, and they have a Ukulele Workshop, and at the end of the third day, the whole class play a tune together on stage. Everyone gets to have a go, even if they have only mastered one chord - it's a great sense of fun and community, so I'd say give it a go.
