The department really began to expand in 1856 when the company pioneered infantile insurance, allowing parents to insure the lives of children under the age of ten. By keeping statistical records about policy-holders, Prudential was able to calculate accurate premium rates and improve the benefits payable on policies. By the turn of the century one third of the population was insured with "the Pru". By the mid-1870s, the company started to employ lady clerks and use "modern" calculators and typewriters.
