Given an ordered set of groups or classes and percentages for each one, the cumulative percentage is the running total of the percentage values as you go along the groups or classes.
Cumulative risks are risks that increase with each added risk.
Yes.We do include vaccinated population from population at risk calculating cumulative incidence.
the answer is related risks that increase in effect with each added risk.
Death
comulative risks are related risks that increase with each added risk. An example is using a cell phone while driving.
Here is an example: Fire fighters face many hazards. Explosions, fire, toxic inhalations, etc. The cumulative risk of being a fire fighters is immense.
example for cumulative incidence(Risk)...... Number of new cases/Population at risk 28 patient in two years/1000 person at risk which means 2.8% the IR for the same example 14 patient / 1 year
Occur by the increase of effect of one risk or of each added risk
Cumulative incidence is a measure of frequency, as in epidemiology where it is a measure of disease frequency during a period of time. Cumulative incidence is the incidence calculated using a period of time during which all of the individuals in the population are considered to be at risk for the outcome. It is sometimes referred to as the incidence proportion or the attack rate. Cumulative incidence is calculated by the number of new cases during a period divided by the number of people at risk in the population at the beginning of the study.

Suppose you have a set of ordinal values and numbers of occurrences of the values then the number of occurrence as a percentage of the total number of occurrences is the percentage corresponding to that particular ordinal value. The cumulative percent is the sum of the percentages up to and including that ordinal value.
The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative percentages coarser than each of the standard sieves used for segregating sand and dividing the cumulative percentage by 100.
