What type of data is considered 'Specific' in data collection and analysis?

In the context of data collection and analysis, 'Specific' data refers to detailed information that pertains directly to a certain property or location. This encompasses site and improvement data, which includes characteristics of the land and any structures on it. This type of data is crucial for a tax assessor because it allows for a precise evaluation of a property's value based on its unique features, zoning, size, and the specifics of any improvements made.

Unlike national trends or general economic indicators, which provide broad insights that may not directly relate to an individual property's valuation, specific data is actionable and relevant for making specific assessments. Comparative sales data, while useful, often provides context and may indicate market trends, but still lacks the granularity that site and improvement data offers for an accurate property valuation. Thus, focusing on site and improvement data gives a clearer and more tailored understanding of each property’s worth.
