This is a historical map of Pittsburgh from the Pittsburgh Survey, dated 1908 and designed under the direction of Shelby M. Harrison. The map represents the ratio of the cost of new dwellings erected in 1903, 1904, and 1905 to the total assessed value of real property in each ward in Pittsburgh in 1903.

The map is divided into ward regions labeled with corresponding numbers. Colored shading and patterns distinguish specific percentages as noted in the legend (key):

• I: Under 0.9%
• II: 1% to 1.9%
• III: 2% to 2.9%
• IV: 3% to 3.9%
• V: 4% to 4.9%
• VI: 5% to 6.9%
• VII: 7% to 8.9%

These percentages represent the cost-to-value ratio for the areas shown on the map.

The map includes major waterways, such as the Ohio River, Allegheny River, and Monongahela River, which are labeled for context. It appears to focus on urban regions, with more densely shaded areas in locations where the ratio is higher.

The image is an old map from 1900 titled "The Pittsburgh Survey," created under the direction of Shelby M. Harrison. It depicts sections of Pittsburgh and Allegheny with various areas shaded in different colors and patterns to show data about housing costs.

The map specifically illustrates the ratio of the cost of new dwellings erected in 1893, 1894, and 1895 to the total assessed value of real property in each ward in 1893. The regions are labeled with Roman numerals, which correspond to different percentage ranges shown in the key on the left side of the map.

The key indicates seven categories for the "percent of cost of new buildings to value of property":

• Category I: Under 0.9%
• Category II: 1% to 1.9%
• Category III: 2% to 2.9%
• Category IV: 3% to 3.9%
• Category V: 4% to 4.9%
• Category VI: 5% to 6.9%
• Category VII: 7% to 8.9%

This categorization is shown on the map with different shades and patterns, helping to visualize where new construction was most economically significant in relation to existing property values at the time. The map also shows major water bodies, including the Ohio, Allegheny, and Monongahela Rivers, which help orient the city geographically.

This is a historical map titled "The Pittsburgh Survey" from 1895, created by Shelby M. Harrison. It shows Pittsburgh and its surrounding areas, particularly focusing on the ratio of cost of new dwellings to total assessed property value across different wards of the city.

The map uses different cross-hatching patterns to indicate seven different percentage ranges, from under 0.9% (Level I) up to 7-8.9% (Level VII). The Ohio River and Monongahela River are clearly visible on the map, with Allegheny marked on the left side.

The map is drawn in a simple, monochromatic style typical of the period, with various shading patterns to distinguish between different zones. The darker shaded areas indicate higher percentages of new building costs relative to total property values, while lighter or unshaded areas represent lower percentages.

This type of map would have been valuable for understanding urban development and property values in Pittsburgh during the late 19th century, particularly during a period of significant industrial growth in the city.
