While 'Il y a' means 'there are', French speakers prefer 'on est' or 'nous sommes' when they are including themselves in the count.

Cultural Tip
In modern French, 'on' has almost entirely replaced 'nous' in speech. When talking about family, French people typically refer to the nuclear family; if you want to include extended family, you might specify 'ma famille élargie'.
