![]() ![]() It is important to note that choropleth maps should use standardized data values ( e.g., ratios or percentages) rather than absolute values. A logical sequence of colours or grey tones is then applied to each class. 0 Comments Two common thematic maps produced at Statistics Canada are dot maps and choropleth Footnote 1 maps. Usually, the data are grouped into a limited number of classes, with each class representing a range of data values. The choropleth method symbolizes statistical data as they occur within the boundaries of predefined geographic units (such as census divisions or census tracts). The term 'choropleth' is derived from the Greek choros, for place, and plethos, for magnitude.Prior to 1976, thematic maps were generated using manual cartographic methods. ![]() Refer to related definitions of cartographic boundary files (CBFs) ecumene and reference map. Thematic maps can be used for exploratory spatial data analysis, confirming hypotheses, synthesizing spatial data by revealing patterns and relationships, and data presentation. To ensure confidentiality, all census data are subject to random rounding and/or data suppression. The ecumene concept is generally used for dot and choropleth maps, to ensure that the spatial representation of census data is limited to inhabited land. is 332 million (2020), and the country ranks 146th in population density (87 pop/mi2 or 34 pop/km2). per square mile has grown from 4.5 in 1790 to 87.4 in 2010. During this time, the number of people living in the U.S. Two common thematic maps produced at Statistics Canada are dot maps and choropleth 1 maps. Population density has been monitored for more than 200 years in the U.S. Desk-top geographic information systems or computer-mapping packages are typically used to generate thematic maps. Normally, the two are available as digital files, such as a cartographic boundary file and census data. ![]() Thematic maps normally include some locational or reference information, such as place names or major water bodies, to help map readers familiarize themselves with the geographic area covered on the map.Īll thematic maps are composed of two important elements: a base map and statistical data. A thematic map focuses on the spatial variability of a specific distribution or theme (such as population density or average annual income), whereas a reference map focuses on the location and names of features. The map may be qualitative in nature ( e.g., predominant farm types) or quantitative ( e.g., percentage population change).Ģ011, 2006, 2001, 1996, 1991, 1986, 1981, 1976, 1971, 1966, 1961 RemarksĪ thematic map is also called a special-purpose, single-topic, or statistical map.
