Note
- Standardized Incidence Rate：Our map uses age-adjusted incidence rate to compare different area and removed the effect of age structure. The method of calculating standardized incidence rate is following:
- First, calculate incidence rate, the number of new cases per population, in each age group ( 18 groups in total: 0–4, 5–9, 10–14,…,80–84,and more then 85).
- Multiply each incidence rate byWorld Standard Population (2000) in each age group to get age-sepcific standardized incidence rates.
- Sum across all the age-sepcific standardized incidence rates to get the standardized incidence rates.
- Local Moran's I：Local Moran's I is the measurement of the relevance among an individual region and adjacent areas. When the value of Local Moran’s I statistic is positive, it means positive correlation. Local Moran’s I（
） is computed as:
,
where,is Local Moran’s I statistic of town i,
is the standardized incidence r of town i,
is the mean of standardized incidence rates of towns,
is the spatial weight between town i and j, and n is the total number of towns.
The z score for the statistics are computed as:
where Z score represents the statistical significance of the computed index value,
is expected Value, 
is variance, and
