The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The effect of nonsampling error is not represented in these tables.Data Processing Notes:Boundaries come from the Cartographic Boundaries via US Census TIGER geodatabases. Boundaries are updated at the same time as the data updates, and the boundary vintage appropriately matches the data vintage as specified by the Census. These are Census boundaries with water and/or coastlines clipped for cartographic purposes. For state and county boundaries, the water and coastlines are derived from the coastlines of the 500k TIGER Cartographic Boundary Shapefiles.

Percentages and derived counts, and associated margins of error, are calculated values (that can be identified by the "_calc_" stub in the field name), and abide by the specifications defined by the American Community Survey.Field alias names were created based on the Table Shells.Margin of error (MOE) values of -555555555 in the API (or "*****" (five asterisks) on data.census.gov) are displayed as 0 in this dataset. The estimates associated with these MOEs have been controlled to independent counts in the ACS weighting and have zero sampling error. So, the MOEs are effectively zeroes, and are treated as zeroes in MOE calculations. Other negative values on the API, such as -222222222, -666666666, -888888888, and -999999999, all represent estimates or MOEs that can't be calculated or can't be published, usually due to small sample sizes. All of these are rendered in this dataset as null (blank) values.

ISO is an independent advisory organization that collects information on a community's building-code adoption and enforcement services in order to provide a ranking for insurance companies. ISO assigns a Building Code Effectiveness Classification from 1 to 10 based on the data collected. Class 1 represents exemplary commitment to building-code enforcement. Municipalities with better rankings are lower risk, and their residents' insurance rates can reflect that. The prospect of minimizing catastrophe-related damage and ultimately lowering insurance costs gives communities an incentive to enforce their building codes rigorously.

Geospatial Analytics in Insurance Market Outlook

According to our latest research, the geospatial analytics in insurance market size was valued at USD 2.9 billion in 2024, with a robust compound annual growth rate (CAGR) of 13.8% expected from 2025 to 2033. By the end of the forecast period, the market is projected to reach USD 9.1 billion, driven by increasing adoption of advanced analytics for risk assessment and claims management across the global insurance sector. The rapid integration of geospatial data with core insurance processes is enabling insurers to enhance operational efficiency, improve customer experience, and reduce fraud, which are among the key growth factors fueling this market’s expansion.

The primary growth driver for the geospatial analytics in insurance market is the rising need for precise risk assessment and mitigation strategies. Insurance companies are increasingly leveraging geospatial data to analyze environmental risks such as floods, wildfires, and storms, which significantly impact underwriting and pricing decisions. By integrating satellite imagery, aerial photography, and geographic information systems (GIS), insurers can more accurately evaluate property locations, historical claim patterns, and susceptibility to natural disasters. This granular level of insight not only helps in pricing policies more effectively but also reduces the risk of underwriting losses. Moreover, the increasing frequency and severity of climate-related events have made traditional risk models obsolete, pushing insurers to adopt geospatial analytics as a critical tool for business continuity and resilience.

Another significant factor propelling market growth is the evolving regulatory landscape and the growing emphasis on transparency and compliance within the insurance industry. Regulatory bodies across various regions are mandating the use of data-driven approaches for assessing risk and ensuring fair premium calculations. Geospatial analytics plays a pivotal role in meeting these regulatory requirements by providing verifiable, location-based data that enhances the accuracy of risk evaluation and claim validation. Furthermore, the integration of real-time geospatial data facilitates immediate response to catastrophic events, enabling insurers to streamline claims processing and improve customer satisfaction. As regulations become more stringent, the adoption of geospatial analytics is expected to accelerate, further boosting market growth.

Technological advancements and the proliferation of cloud-based solutions are also contributing to the expansion of the geospatial analytics in insurance market. The advent of artificial intelligence (AI), machine learning, and big data analytics has revolutionized the way geospatial data is collected, processed, and analyzed. Cloud-based geospatial analytics platforms offer scalable and cost-effective solutions, making them accessible to both large enterprises and small and medium-sized insurers. These platforms enable seamless integration with existing insurance management systems, facilitating real-time data sharing and collaboration across departments. The continuous innovation in remote sensing technologies, drones, and IoT devices is further enhancing the quality and granularity of geospatial data, opening new avenues for insurers to optimize their operations and deliver personalized services to their customers.

From a regional perspective, North America continues to dominate the geospatial analytics in insurance market, accounting for the largest revenue share in 2024. The region’s advanced digital infrastructure, high insurance penetration rates, and early adoption of geospatial technologies are key contributors to its market leadership. Europe follows closely, driven by stringent regulatory frameworks and increasing investments in digital transformation initiatives by insurers. Meanwhile, the Asia Pacific region is witnessing the fastest growth, fueled by rapid urbanization, increasing natural disaster occurrences, and rising awareness among insurers about the benefits of geospatial analytics. Latin America and the Middle East & Africa are also emerging as promising markets, albeit at a slower pace, due to gradual technological adoption and evolving insurance landscapes.

Therefore, any measure reported by ACS should not be taken as an exact number – this is why a corresponding margin of error (MOE) is also given for ACS measures. The size of the MOE relative to its corresponding estimate value provides an indication of confidence in the accuracy of each estimate. Each MOE is expressed in the same units as its corresponding measure; for example, if the estimate value is expressed as a number, then its MOE will also be a number; if the estimate value is expressed as a percent, then its MOE will also be a percent. The user should also note that for relatively small geographic areas, such as census tracts shown here, ACS only releases combined 5-year estimates, meaning these estimates represent rolling averages of survey results that were collected over a 5-year span (in this case 2015-2019). Therefore, these data do not represent any one specific point in time or even one specific year. For geographic areas with larger populations, 3-year and 1-year estimates are also available.
