Spatial Concentration and Diversity Flashcards
What is Race?
Refers to the variety of human species based on distinct anatomical traits
Why do we not use Race often anymore?
− Rracial mixing makes the categories of ‘White’, ‘Black’ and ‘Other’ no longer distinct
− The concept of race associated with ideas of social inequality, supremacy and subordination
What is ethnicity?
− Selected cultural and sometimes physical characteristics used to classify people into categories considered to be different from others
− May involve either loose group identity with little or no cultural traditions in common or groups with coherent subcultures with a common place of origin, language, religion and cultural traditions
How is Ethnicity Identified in the UK census?
Self Reported
What factors can make up ethnicity?
Multifaceted, some or all of: − Country of birth − Nationality − Language spoken at home − Parents’ country of birth − Skin colour − National origin − Racial group − Religion
Why do we need to standardise data?
Looking at raw counts of BME groups can often lead to misinformed spatial analysis
What is a Location Quotient?
A Location quotient (LQ) is a valuable way of quantifying how concentrated a particular industry, cluster, occupation, or demographic group is in a region as compared to the nation. It can reveal what makes a particular region “unique” in comparison to the national average.”
What does (Pei / P*i) * 100 show?
Ethnic group percentage
What is the equation for Location Quotients?
(Pei / Pi) / (Pe / P**)
What is ethnic diversity?
− Measures of the mix of ethnic groups in an area
− A measure that “reports the percentage of times that two randomly selected people would differ by ethnicity” (Brewer and Suchan, 2001, p. 22)
What is the index of dissimilarity?
− Designed to measure an unequal geographical spread, and is often interpreted as an indicator of the proportion of one group’s population who would have to move to be distributed across areas in the same way as the rest of the population:
− IoD between two groups, White (w) and Black (b) is: IoD(w and b) = 0.5 Σ |(Pwi / Pw)-(Pbi / Pb)|
