What is an AVERAGE tree?
Can there really be such a thing in terms of ALL trees?
You refer to a birch. There a bunch of birches:
Birches of North America include
Betula alleghaniensis - Yellow Birch (B. lutea)
Betula cordifolia - Mountain Paper Birch
Betula glandulosa - American Dwarf Birch
Betula lenta - Sweet Birch, Cherry Birch, or Black Birch
Betula lenta subsp. uber - Virginia Round-Leaf Birch (endemic, Cressy Creek, Smyth County, Virginia)
Betula michauxii - Newfoundland Dwarf Birch
Betula nana - Dwarf Birch or Bog Birch (also in northern Europe and Asia)
Betula neoalaskana - Alaska Birch or Yukon Birch
Betula nigra - River Birch or Black Birch
Betula occidentalis - Water Birch or Red Birch (B. fontinalis)
Betula papyrifera - Paper Birch, Canoe Birch or American White Birch
Betula populifolia - Gray Birch
Betula pumila - Swamp Birch

So what is an average birch?
Well then I suppose one would need to pick a specific birch to be able to quantify that group. Then one would be talking about all the things that influence that group in terms of health, which in turn influences everything about that specific entity including location, soil, water, exposure, grouping, polutants, nutrients, diesease impact, insect intrusion, induced physical damage from wind, snow, etc and etc.
All of the environmental aspects will influence a tree's life span. Impact of any one of those upon a single tree will influence that particular tree's life.

A birch is any of about 40 species of SHORT-LIVED, ornamental and timber trees and shrubs constituting the genus Betula (family Betulaceae), distributed throughout cool regions of the Northern Hemisphere. So, in terms of ALL trees, the birch has a relitively short life.
Birches are usually the first to establish in cleared land, but start to die once other trees move in and offer shade. The trees will average a height of 70' and a diameter of 2'.
So, birches are quicker to establish and have a fast growth rate. This growth habit gives us an idea as to longevity in terms of the guide line that states, "Grow fast - die early; Grow slow - long life." Compare that saying to what we know of trees, Elms, birch, soft-wood pines life span vs. Oak, Sequoia, Olive.

Reference the following at: http://www.na.fs.fed.us/spfo/pubs/howtos/ht_birch/ht_birch.htm
A healthy birch tree should be able to survive and thrive for 40-50 years. In many yards, however, it is not unusual for birch trees, especially the white-barked birches, to die well before reaching 20 years of age.
