If you prefer to use the CSS selector approach, you can do this:
var c = $('#france').is(":checked");
Or:
var c = $('#france').prop("checked");
.prop() is probably the better choice.
From here: http://api.jquery.com/prop/ - is() and prop(), while they retrieve different things, both work reliably. While using attr() has a different meaning - it retrieves only the default value

I have created a fiddle here for you.

Below code you used for checking the Checkbox checked property is correct.
if ($("#france").is(':checked')) {
alert("France Selected");
}
EDIT: When you click again on Countries when States fade in, the checked is still true and it shows the alert.

Hope this can help you..
var title = $(".title-search");
title.click( function(){
var selected = '';
$('.s_list input:checked').each(function() {
selected += $(this).attr('id') + ',';
});
$(".state").fadeToggle('fast');
if(selected.length)
alert('selected: ' + selected);
});
