Why Isn't It Better For My Wife And I To Start Drawing Benefits At Age 66?

My wife and I turn 66 in October, 2016. My wife is not eligible, on her own, for Social Security benefits. According to the SSA website I would receive $2,617/month at age 66 if I filed for benefits. Based on my understanding of Spousal benefits my wife would receive $1,308/month. Together this would equal $47,100 annually or a total of $188,400 by the time we reach age 70. If we were to defer receiving benefits until we reach age 70 our annual amount would total $57,912 (my $3,518/month and my wife's $1,308/month) resulting in a $10,812 annual increase.
