Manager Longevity
I ran some figures on the 2005, 1995 and 1985 seasons in regards to major league baseball managers. I was looking to determine if the state of major league managing in 2005 was in more or less flux as compared to the other seasons. Are teams placing more of a premium on managerial experience or looking to hire fresh hands? Was there a higher or lower turnover in 2005 as compared to 1995 and 1985? What are the tenure trends of managers for the teams they are currently managing?
Fully knowing that a three year sample is minute I went ahead anyway and ran a quick and dirty analysis just for fun and came up with three determinents to try and answer my questions. First, determine the average age of managers during a particular season. Secondly, calculate the number of years they'd been managing their current team and thirdly find the number of years they'd managed during their careers.

The study includes all men who managed teams as determined by baseball-reference.
Average Age of Managers
The 2005 average manager age was two and a half years older than 1995 or 1985's average ages. Not too much disparity between the years.
2005 ---- 52.7
1995 -----49.6
1985 -----50.0
Eight of the thirty-five managers in 2005 five were over age sixty. There were only four such managers in '95 and a paltry two in 1985. But managers in their thirties were even rarer. Bobby Valentine was 35 when he earned his first major league managing position in 1985 for the Texas Rangers. Terry Bevington and Buck Showalter were in their late thirties during 1995 and Eric Wedge was 37 this past season.
Average Numbers of Years Managing Current Team
The results to this question can help to determine how prevalent manager tenure was in a particular year.
2005 -----2.7 years
1995 -----3.8
1985 -----1.9
There's some nice disparity in this figure. The uptick in 1995 to a nearly four year average tenure (which seems very, very high) was greatly due to the nineteen years Tommy Lasorda had spent in Los Angeles and the sixteen years Sparky Anderson had spent in Detroit. Without those two in the calculation the average drops down to 2.7 years -- just like in 2005. Tommy Lasorda and Pittsburg's Chuck Tanner were tops in tenure entering the 1985 season with eight years a piece with their respective teams.
Average Number of Years Managing in Career
The results to this question speaks to the prevalence (or lack of prevalence) of teams looking for experience in their field managers.
2005 -----6.8
1995 -----6.1
1985 -----5.9
Ultimately not a drastic difference between the three years. Tony LaRussa's 26 (2005), Sparky Anderson's 25 (1995) and Gene Mauch's 23 (1985) years of managing led their respective seasons.
