The average age of producers as well as that of the major equity holders changed little from the 1998 Pork Industry Structure Study. Table 17a shows the average age of medium-sized producers (1,000 to 49,999 hogs annually) in the 2001 Industry Structure Study was 47.6 years compared to 47.5 years in 1998. Likewise, the major equity holder was 49 compared to 48.8 in 1998. Because the surveys are three years apart, the constant age indicates that younger producers are entering as older producers leave the business. The age distribution shows about the same percentage of producers that are 30 years and younger, and a higher percentage of 41-to-50-year olds compared to 1998 (Table 17b).
