AoD
- population pyramid per decade since some starting date,
- death rate per age per decade (probably will be taken a priori),
- algorithm starting date (a priori),
- starting population pyramid (a priori),
- depopulation per decade (some factors of it might be taken a priori).
DoD
- population per decade since some starting date,
- death rate per decade (probably will be taken a priori),
- depopulation per decade (some factors of it might be taken a priori).
Let's take the DoD problem first. Here are some rough thoughts about the model of the problem:
population(t + 1) = population(t) * (1 - pass_away_rate(t)) + real_growth(t) + migration(t)real_growth(t) = natural_growth(t) * enfant_survavibility_factor(t)natural_growth(t) = alive_population(t) * mortality_rate(t) * wraith_turn_factor(t)enfant_survavibility_factor(t) = 1 - enfant_oblivion_rate(t) - enfant_decorpsing_rate(t)pass_away_rate(t) = senior_oblivion_rate(t) + senior_ascension_rate(t) + senior_decorpsing_rate(t)
For more actual work on the model, look at #7
How many Restless are there in the Necropolis of Warsaw?
Actually, there are two questions:
AoD) What is the age of death of how many wraiths across the population of Necropolis? AoD alters demeanor & nature of wraiths' psyche & shadow.
DoD) What is the date of death of how many wraiths? DoD defines culture context of a character and certain aspects of his/her social position.
Both questions share the same demographic model of getting to the Shadowlands, migrations & Ascension/Oblivion/decorpsing and differs in entry data.
