A bit dated, but it seems that current has about a $1B total revenue overall (circa 2015). In my very cursorily search, I couldn't find any more specific data, but $1B total revenue from SD resident data seems a bit high to me (kudos to anyone however that can find more current data). Pure speculation, but perhaps the above article was talking about overall revenue and not only SD data revenue?
