No, they need not be.
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.
Cumulative risk refers to the combined impact of multiple risk factors or exposures over time, which can amplify the likelihood of negative outcomes. It is important to assess cumulative risk to understand how various elements—such as environmental, social, and behavioral factors—interact and contribute to overall risk levels. By evaluating cumulative risk, individuals and organizations can better devise strategies for prevention and intervention.
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.
comulative risks are related risks that increase with each added risk. An example is using a cell phone while driving.

To plot a Lorenz curve, first, gather the data for the variable of interest (e.g., income) and sort it in ascending order. Next, calculate the cumulative percentages of the total population and the cumulative percentages of the total income, plotting these values on a graph where the x-axis represents the cumulative population percentage and the y-axis represents the cumulative income percentage. The resulting curve illustrates income distribution, with the line of equality (45-degree line) serving as a reference for perfect equality. The further the Lorenz curve is from this line, the greater the inequality in the distribution.
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
Risk behavior refers to specific actions or decisions that increase the likelihood of negative outcomes, such as substance abuse or reckless driving. In contrast, cumulative risk refers to the overall level of risk an individual faces due to the accumulation of multiple risk behaviors and environmental factors over time. While risk behavior focuses on individual actions, cumulative risk emphasizes the combined effect of various risks on a person's well-being. Understanding both concepts is essential for effectively addressing and mitigating risks in health and safety contexts.
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.
