Rīgas Svētki (Riga Festival) is an annual event to celebrate Riga's birthday. Today Riga became 811 years old :)
Birthday is always a good reason to make some inventory.
So, for the last year Riga population went down from 717,371 to 713,016 people (-4,355 or -0,61%), but
Riga district population (including cities inside) has grown from 940,725 to 942,002 (+1,277 or +0,14%)
However Latvia population became less for -9,600 or -0,42% of people (from 2,270,894 to 2,261,294)
