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.[11][12] 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.[13] This system was greatly expanded after the Second World War under the influence of the Beveridge Report, to form the first modern welfare state.[11][14]
RV insurance isn’t the same thing as auto insurance, though many providers give you the option to bundle the two. But RVs have specialized concerns. To start, they can carry many more people than cars, and they cost more to repair. In addition to basic coverage, RV insurance can also offer more extensive protection, with coverage for personal belongings, emergency expenses for lodging, and higher damage rates.

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.[24] 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.
An insurance underwriter's job is to evaluate a given risk as to the likelihood that a loss will occur. Any factor that causes a greater likelihood of loss should theoretically be charged a higher rate. This basic principle of insurance must be followed if insurance companies are to remain solvent.[citation needed] Thus, "discrimination" against (i.e., negative differential treatment of) potential insureds in the risk evaluation and premium-setting process is a necessary by-product of the fundamentals of insurance underwriting. For instance, insurers charge older people significantly higher premiums than they charge younger people for term life insurance. Older people are thus treated differently from younger people (i.e., a distinction is made, discrimination occurs). The rationale for the differential treatment goes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk of loss (the insured's death) is greater in any given period of time and therefore the risk premium must be higher to cover the greater risk. However, treating insureds differently when there is no actuarially sound reason for doing so is unlawful discrimination.
Large loss: The size of the loss must be meaningful from the perspective of the insured. Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses, these latter costs may be several times the size of the expected cost of losses. There is hardly any point in paying such costs unless the protection offered has real value to a buyer.
Insurance policies can be complex and some policyholders may not understand all the fees and coverages included in a policy. As a result, people may buy policies on unfavorable terms. In response to these issues, many countries have enacted detailed statutory and regulatory regimes governing every aspect of the insurance business, including minimum standards for policies and the ways in which they may be advertised and sold.

Large number of similar exposure units: Since insurance operates through pooling resources, the majority of insurance policies are provided for individual members of large classes, allowing insurers to benefit from the law of large numbers in which predicted losses are similar to the actual losses. Exceptions include Lloyd's of London, which is famous for ensuring the life or health of actors, sports figures, and other famous individuals. However, all exposures will have particular differences, which may lead to different premium rates.

One of Progressive’s add-on coverages includes a “disappearing deductible” option. This means that each year you don’t file a claim, Progressive will drop your rate by 25%. With this method, the company boasts that you could eventually have a $0 deductible. But it only stays this way as long as you haven’t filed a claim — if you do, your deductible will go right back up. Safeco also incentivizes safe driving with low deductibles. Safeco will reduce your collision deductible by $100 each year you don’t have a claim, but this incentive caps at $500.

The main difference between collision and comprehensive coverage comes down to the question of what the driver controls. Collision insurance will cover events within a motorist's control or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," or things that are typically out of your control when driving. These can include events such as a spooked deer, a heavy hailstorm, or a carjacking.
