Proprietary databases of property values

Verisk has developed databases of estimated numbers, types, and values of properties for residential and commercial properties and, in some countries, automobiles.

These estimates are made at a high level of resolution and reflect the mix of construction and occupancy types in each geographic region. This detailed data is then aggregated to county or equivalent to match your submission detail. These databases have been constructed from a wide range of data sources and reflect the estimated total replacement cost.

Databases also contain:

  • Payroll and number of employees detail for use in estimating workers' compensation loss potential from earthquakes and terrorism.

    Number of risks (population data) and default benefit levels (rates) for pandemic analysis.

The numbers of properties, estimated property values, and other assumptions underlying the database are generally updated on an annual basis. The property value databases are developed, maintained and enhanced through an ongoing process of data collection, synthesis and analysis. Much of the information required to develop the estimated values is acquired each year from governmental statistics agencies and private firms that specialize in this type of information. For example, primary data sources in the United States include the U.S. Census Bureau, Dunn & Bradstreet, Claritas, the Insurance Information Institute, and R.S. Means.

Verisk's property databases are used in Touchstone Re to produce industry loss estimates and as the basis for calculating individual company market shares.
