Deer numbers in general way down in Dad's area (he's near Albia, Zone 5). There has been a steady decline in both numbers of deer and overall quality of older bucks in general in that area since he moved out there - 12-15 years ago. He has been taking a significant amount of does from the property the last several years - as have been the neighbors - and, of course, the deer are hammered big time during the gun seasons - and the overall population is about right, in his opinion, but probably down 50% from the high point 10 yrs ago.
The more distressing part is the decline in mature bucks. That area is hit really hard by the "wannabe trophy hunter" types. Lots of TV crews and magazine writers in the area. Some of these guys are famous for hunting mature bucks until the last couple days then shooting "whatever" for the video camera. There are still plenty of younger bucks, and some older deer, but not nearly like it was 5-10 yrs ago.
Of course its all relative....if you are from an area with few good deer you will see better deer than you are used to, but it ain't the Iowa of 10 years ago.
