By the late 19th century governments began to initiate national insurance programs against sickness and old age. Germany built on a tradition of welfare programs in Prussia and Saxony that began as early as in the 1840s. In the 1880s Chancellor Otto von Bismarck introduced old age pensions, accident insurance and medical care that formed the basis for Germany's welfare state. In Britain more extensive legislation was introduced by the Liberal government in the 1911 National Insurance Act. This gave the British working classes the first contributory system of insurance against illness and unemployment. This system was greatly expanded after the Second World War under the influence of the Beveridge Report, to form the first modern welfare state.
At the most basic level, initial ratemaking involves looking at the frequency and severity of insured perils and the expected average payout resulting from these perils. Thereafter an insurance company will collect historical loss data, bring the loss data to present value, and compare these prior losses to the premium collected in order to assess rate adequacy. Loss ratios and expense loads are also used. Rating for different risk characteristics involves at the most basic level comparing the losses with "loss relativities"—a policy with twice as many losses would therefore be charged twice as much. More complex multivariate analyses are sometimes used when multiple characteristics are involved and a univariate analysis could produce confounded results. Other statistical methods may be used in assessing the probability of future losses.
Know when to cut coverage. Don’t strip away coverage just for the sake of cheaper insurance. You’ll need full coverage car insurance to satisfy the terms of an auto loan, and you’ll want it as long as your car would be a financial burden to replace. But for older cars, you can drop comprehensive and collision coverage, which only pay out up to your car’s current value, minus the deductible.
