Figure 2
Mixing patterns by age in the UK.
Representations in logarithmic scale of contact matrices by one-year age brackets for the United Kingdom in the different social settings. Frequency of contacts (in arbitrary units) increases from blue to red. a Household. b School. c Workplace. d General community. e The total matrix obtained as a linear combination of the matrices represented in a–d; the coefficients used are the proportions of transmission in the four settings: 0.3 in households, 0.18 in schools, 0.19 in workplaces and 0.33 in the general community [3], [11], [42], [44]–[46]. f Proportions of contacts with individuals of the same age group, from the total matrix.
