Which four data products and services does ArcGIS Online provide?

ArcGIS Online provides a variety of data products and services that enhance the capabilities of geographic information systems. One of the primary offerings is demographic data, which includes information on population characteristics, economic trends, and social factors. This data is essential for businesses, government agencies, and organizations that require insights into communities for planning, research, and decision-making.

Demographic data available in ArcGIS Online can be used to create thematic maps, conduct spatial analysis, and support various applications, from market analysis to public health assessments. The service enables users to access up-to-date demographic statistics that can be integrated into their GIS projects for better understanding and visualization of trends and patterns.

Other options like registries, imagery, and data enhancement may involve specialized applications or external datasets, but demographic data represents a foundational layer deeply integrated into ArcGIS Online for general use, making it a key component for many GIS analyses and projects.
