Target Population Functions:

These functions do not require to access the KHIS server the project and calculate the target population guided the Kenya housing and population census 2019 and the Kenya National Cancer Screening guidelines 2019.

The functions include: get_cervical_target_population(), get_colorectal_target_population(), get_breast_cbe_target_population() and get_breast_mammogram_target_population().

If these function do not meet your criteria you can make your target population using the get_filtered_population().
