To report the series, The Sun asked the city for the net tax bill and any credits for each of the city's 236,000 properties. After officials said they lacked the technical means to produce that level of detail, The Sun built its own database, using an automated process called "data scraping." Information was copied, one record at a time, from individual tax records publicly available on the city's website.
Jamie Smith Hopkins, a Baltimore Sun reporter since 1999, writes about the housing market and runs the Real Estate Wonk blog. Her coverage has won national awards, including a "Best in Business" recognition this year from the Society of American Business Editors and Writers.
Reporter Scott Calvert joined The Sun in 2000. He was the newspaper's Africa correspondent from 2005 to late 2007, and last year his investigation of a Baltimore mental health clinic prompted state health officials to develop new oversight measures.
