Examining assessment equity with the Gini index in Ontario, Canada
No full textExploring research from the Journal of Property Tax Assessment & Administration, the Municipal Property Assessment Corporation (MPAC), in Ontario, Canada, uses the Gini Index as a complementary tool for measuring property assessment equity. Unlike the traditional measures (CODs, PRB and PRD), Gini Indices calculations do not rely on sales ratios but rather on a ranked cumulative distribution within the values themselves (prices and/or assessment) for its calculation. MPAC tested Gini Indices against current measures of equity for 129 residential market areas and examined the differences with the traditional measures of equity. An advantage of using Gini Indices is that the results are easily decomposable into distributive effects (vertical and horizontal equity measures), subgroup effects (price level or economic neighbourhood group comparison), and factor effects (regression independent variables used in model building). This granular decomposition allows MPAC to track sources of inequalities within market areas. Gini also provides a standard measure of horizontal equity across different market areas, unlike COD which requires different standards for different markets
Sketch Inspect: Faster, Easier Sketch Verification
No full textFaster, easier sketch verification is finally here! Sketch Inspect, a new software solution from EagleView, is revolutionizing property sketch verification. Using machine learning and powerful computer algorithms, Sketch Inspect superimposes property sketches from a CAMA system on top of aerial imagery, helping assessors find properties with inaccurate and missing property sketches and prioritize which properties to update. This presentation from EagleView includes a demonstration of Sketch Inspect and an overview of its benefits, including data accuracy, workflow efficiency and cost savings
