Time allocation studies are frequently used to describe gender and age based labor patterns. In farming systems research (FSR), labor patterns have been analyzed to support a wide range of findings including the determination of peak labor periods (Maxwell 1984; Price and Barker 1978), income opportunities for female farmers (Burfisher and Horenstein 1985), the contribution of children to farm production (Navera 1978), crop labor investments (Barlett 1980), seasonal fluctuations in agricultural and nonagricultural activities (Norman et al. 1981), and inter household differences in the family cycle (Cadelina 1985).
