I live in Toronto, Canada (pretty urbanised) and prices have been steadily going up for ages now. The multiplex thing really kicked in about maybe six or seven years ago, and since then, they've dominated the scene. Smaller theatres in suburbia have kinda all faded out and died. They used to be really cheap, adult was $4 and children was $2.50 but since those disappeared, they've been replaced by these behemoths that are like 20 theatres or something. Evenings are outrageously expensive (think $13.50/person) and even during the days, it's like nine, ten bucks. Tuesday tickets aren't much better, usually the same price as matinees.
However, there has been a rise in cheaper movie theatres across the greater metropolitan area (Rainbow Cinemas), and that's like $4.50 during the day and $7.50 in the evenings which is decent. Downtown theatres are still doing well because they play all the small obscure films that the cityphites and cinephiles love, and those aren't too expensive...maybe $6-8 or so.
