This is a historical map titled "Map Showing Ratio of New Dwellings Erected in 1905, 1906 and 1907 to the Total Number of Buildings Standing Feb. 1, 1906" from the Pittsburgh Survey, published under the direction of Shelby M. Harrison in 1908. It visually represents the percentages of new dwellings constructed within specific neighborhoods of Pittsburgh during the indicated years.

The map divides the city into distinct regions, labeled with Roman numerals (I, II, III, IV, V, VI), each area corresponding to a percentage range of new dwellings relative to the total building stock. A key at the bottom-left corner associates these Roman numerals with percentages as follows:

• I: Under 5%
• II: 5%–7.9%
• III: 8%–12.9%
• IV: 13%–15.9%
• V: 16%–18.9%
• VI: 22%–20.9%

Different shading or patterns are applied to regions based on their percentage range, illustrating varying levels of residential construction across Pittsburgh. The map emphasizes industrial and urban development trends during the early 20th century, with landmarks such as the Allegheny River, Monongahela River, and Ohio River defining the city's layout.
