At this point you should have a file containing the following variables, perhaps under different names: ageband sex year crudeincrate refpopulationcount Then, for each year, calculate the weighted average of the year's crude incidence rates, using the reference population counts as weights, as follows. dstdize Direct and indirect standardization using(lename) use standard population from Stata dataset base(# jstring) use standard population from a value of grouping variable Comparing the standardized rates indicates that the Swedes have a slightly lower mortality rate.
Nov 05, 2014 I have a dataset containing data from people in many regions and I want to calculate agestandardized rates using a standard population as reference. I have two major things I need help to fix: the first is deriving rates when each line of data refers to just one person and not an agegroup. The second is about inputing the population of Mar 04, 2016 Could you give some hint how could I calculate age standardized rates using standard population let's take 2013 European To get the correct Census age distribution, you need to know two things: the age group of interest (e.
g. all ages, ages 6 and older, adults 20 and older) and how wide the age strata are for adjustment (e. g. 5 year, 10 year or 20 year age intervals).
Age Standardization and Population Counts. Continuous NHANES Web Tutorial. Using the Tutorial. Task 1: Calculate AgeStandardized Estimates. How to Generate AgeAdjusted Prevalence Rates in Stata; OPTIONAL: How to Generate AgeAdjusted Means in Stata; In this example we are calculating ageadjusted incidence rates (ageadjusted to the 2000 U. S. Standard Population (Census P )) for all malignant cancers. These rates are calculated for black females diagnosed from in the SEER 9 registries.
For each combination of stratavars you will need to indicate the population in other variable (i. e. popvar). Groupvars define different populations (e. g. cities, years, etc. ) for comparing the rates. The procedure will produce standardized rates of the event.
