“…Studies in the 1950s showed children were taller on average where the skill level of the father was greater (Acheson & Hewitt, 1954;Douglas & Blomfield, 1958). More recent work has confirmed these findings with statistically significant differences in mean height between social classes at most ages tested (Tanner, 1962;Christiansen, Mora & Herrera, 1975;Neligan & Prudham, 1976;Davie, Butler & Goldstein, 1972;Collins & Weiner, 1977;Topp et al, 1970;Miller et al, 1960).
