This dataset illustrates the largest difference between high and low temperatures and the smallest difference between high and low temperatures in cities with 50,000 people or more. A value of -1 means that the data was not applicable. Also included are the rankings, the inverse ranking to be used for mapping purposes, the popualtion, the name of city and state, and the temperature degree difference.

This data represents the Oregon City Limit boundaries. Each city limit is defined as a continuous area within the statutory boundary of an incorporated city, which is the smallest subdivision of an annexed area. It is represented as spatial data (polygon with label point). Purpose: The use of city limits information was identified as a need for general planning purposes within ODOT. It was determined that this would be a frequently used data set that needed to be both spatially referenced and attributed in a GIS base layer. The decision was made to create a statewide coverage of the boundary outlining the city limits for each of the 242 incorporated cities. An incorporated city may have multiple areas that are not contiguous. Each such area is represented separately with its own polygon. The area of the city limits will be calculated from the polygons created. For assessment and taxation purposes, the boundary change process has two key dates. One is the effective date of the boundary change. The other is the filing deadline with the Department of Revenue. While both of these dates relate to boundary changes, they operate independently. The two key dates are March 31 and July 1. These dates help determine the property affected by a boundary change. The district must file its boundary change documents in final approved form to the Department of Revenue Cadastral Information Systems Unit by March 31 and obtain a notice of approval. In order for a district to extend its tax rate to an annexed territory, the district?s annexation must be effective on or before July 1.

Abstract: A continuous area within the statutory boundary of an incorporated city, which is the smallest subdivision of an annexed area. It is represented as spatial data (polygon with label point). The use of city limits information was identified as a need for general planning purposes within ODOT. It was determined that this would be a frequently used data set that needed to be both spatially referenced and attributed in a GIS base layer. The decision was made to create a statewide coverage of the boundary outlining the city limits for each of the 241 incorporated cities. An incorporated city may have multiple areas that are not contiguous. Each such area is represented separately with its own polygon. The area of the city limits will be calculated from the polygons created.

In 2023, Washington, D.C. had the highest population density in the United States, with 11,130.69 people per square mile. As a whole, there were about 94.83 residents per square mile in the U.S., and Alaska was the state with the lowest population density, with 1.29 residents per square mile. The problem of population density Simply put, population density is the population of a country divided by the area of the country. While this can be an interesting measure of how many people live in a country and how large the country is, it does not account for the degree of urbanization, or the share of people who live in urban centers. For example, Russia is the largest country in the world and has a comparatively low population, so its population density is very low. However, much of the country is uninhabited, so cities in Russia are much more densely populated than the rest of the country. Urbanization in the United States While the United States is not very densely populated compared to other countries, its population density has increased significantly over the past few decades. The degree of urbanization has also increased, and well over half of the population lives in urban centers.
