The behavioural pattern of Bangladesh labour force is characteristically rural, agrarian, bearing distinct marks of age-sex-regional differentials: inter-censal comparisons reveal no significant rural-urban redistribution or its re-structuring among fields of economic activity during 1961-74. The expected male working life compares favourably with the pattern prevalent in selected developing countries, despite a heavier toll of mortality. Estimated statistics of male labour force dynamics reveal that 71.64% of the entries occur by age 15, death claims 55.6% of the annual depletion below age 55, whereas 53.5% of the retirements occur at age 75 and above. The estimated labour force replacement ratio implies that for every 100 depletions, 275 new entries or 175 net additions take place annually. The current back-log of un-and under employed labour force is estimated at around 9.5 million. The socio-economic-geo-demographic realities make it inevitable that vast majority of the surplus labour force will have to be productively employed within a rural set-up. Basic changes in production relations is to be brought about by building socio-economic infrastructure that will engender small family norm from work-force point of view by gainfully employing that adult working population through optimum exploitation of its productive potentials. A comprehensive policy framework for Bangladesh should incorporate the essentials of an integrated labour force and population policy taking cognizance of the inter-relationship of the economic-demographic variables that regulate the demand and supply of labour force on both quantitative and qualitative perspectives.
