What is crude rate

The estimates for many countries are projections based on extrapolations of levels and trends from earlier years or interpolations of population estimates and projections from the United Nations Population Division. Development relevance The crude mortality rate is a good indicator of the general health status of a geographic area or population.

The crude death rate is not appropriate for comparison of different populations or areas with large differences in age-distributions.

Higher crude death rates can be found in some developed countries, despite high life expectancy, because typically these countries have a much higher proportion of older people, due to lower recent birth rates and lower age-specific mortality rates.

Limitations and exceptions Vital registers are the preferred source for these data, but in many developing countries systems for registering births and deaths are absent or incomplete because of deficiencies in the coverage of events or geographic areas. Many developing countries carry out special household surveys that ask respondents about recent births and deaths. Estimates derived in this way are subject to sampling errors and recall errors. Joint External Debt Hub was updated on November 4, Quarterly Public Sector Debt was updated on November 1, World Development Indicators was updated on October 28, Crude death rate indicates the number of deaths per 1, midyear population.

Crude death rate indicates the number of deaths occurring during the year, per 1, population estimated at midyear. Also, for the formulas used to compute crude rates and their associated standard errors, please reference the following help section: Dependent Variable. The Joinpoint Regression Program requires that you specify parameters that are organized on three tabs: the Input File tab, the Method and Parameters tab, and the Advanced Analysis Tools tab.

The Input File tab specifies the file format of the input data file and some additional settings for the model. Please refer to the Joinpoint program's online help for more information regarding the options on this tab. The Method and Parameters tab specifies the modeling method, constraints on the location s of the joinpoints, number of joinpoints, autocorrelated errors options, model selection method and AAPC confidence intervals.

For this exercise, the default settings on the Method and Parameters tab tab were used. The pairwise comparison is only relevant if you have one or more By Variables defined on the Input File tab. There will also be enhancements to this tab in the future that include multi-group clustering.

A progress meter will be shown on the screen while the Joinpoint calculation engine processes the data and generates the output. Note, it can take a few minutes to execute, depending on the size of the input data file and the options selected.

After execution has completed, Joinpoint opens an output window to display the results. For Pairwise Comparison runs, an additional tab named Comparison will be shown. There is a cohort tree located to the left of the tabs which can be used to traverse the cohorts and various joinpoints in the analysis. The results of your session are not automatically saved. If you close the output window without saving your results, you will need to re-run the analysis.

The results can be saved to a Joinpoint output file i. The results can be sent to a printer, PDF, Word, or Excel by selecting Print from the Output menu, and there are options to customize which elements of the output to include.

The following graph is the result of the session in the example for a maximum of 3 joinpoints. It is a scatter plot of the crude colorectal cancer incidence from SEER, for males and females from to A Joinpoint Model is also drawn on this graph.

In this case, the model is four line segments joined at the joinpoints of , , and The model decreases until , it increases again until , decreases until and then decreases more until The U. Populations for single years of age external icon are summed to form the age groups. Ideally, crude, age-adjusted, and age-specific rates are used to plan for population-based cancer prevention and control interventions.

Crude rates are calculated as follows— Crude and age-specific incidence rates equal the total number of new cancer cases diagnosed in a specific year in the population category of interest, divided by the at-risk population for that category and multiplied by , cancers by primary site or by 1 million International Classification of Childhood Cancer [ICCC] groupings of childhood cancers.

Crude and age-specific death rates equal the total number of cancer deaths during a specific year in the population category of interest, divided by the at-risk population for that category and multiplied by ,
