We confirm below various attributes of the agents that are logged.
We will do this in data.table for speed.

# Age Assignment at Entry
We check below the ages of new agents, and if their initial age assignments and age increments are working correctly.
How many agents are present at the last tick:
agent_dt[tick == last_tick, .N] ## [1] 1000How many agents present at tick 991 entered after model initialization?
agent_dt[tick == 991 & id > 9999, .N] ## [1] 0The mean age of agents at time by time of entry at tick 1:
agent_dt[tick == 1,
.("mean_age_today"=mean(age), .N),
by=.(entry_at_tick),
]At tick 491:
agent_dt[tick == 491,
.("mean_age_today"=mean(age), .N),
by=.(entry_at_tick),
]And at tick 991:
agent_dt[tick == 991,
.("mean_age_today"=mean(age), .N),
by=.(entry_at_tick),
]These data seem to match expectations of aging of newly entering agents. See that at tick 1, only one agent had entered after model initialization. and this agent was 18 years old.
At tick 491, this agent was 19 years old (491-365 years older than 18, rounded), and at tick 991, this agent was 21 years old (991-365 years older than 18, rounded).
So, the aging process seems to work as expected.

by=c("race", "female", "age_groups")][order(race, female, age_groups)][,"prop":=round(N/sum(N)*100, 0)][]How many persons have been ever incarcerated?
To answer this question, we can group the last incarceration times by agent ID. If last incarceration time is -1, the person has never been incarcerated. If last incarceration time is > -1, the person has been incarcerated at least once.
# Group data by agent ID and compute the last incarceration time
last_incarceration_time <- agent_dt[,
.(last_incarceration_time = max(last_incarceration_tick)),
by = id]
# Count the number of agents who have been incarcerated at least once
n_ever_incarcerated <- sum(last_incarceration_time$last_incarceration_time != -1)
# Compute the proportion of agents who have been incarcerated at least once
prop_ever_incarcerated <- n_ever_incarcerated / nrow(last_incarceration_time)
# Agents who have been incarcerated at least once
ever_incarcerated_times <- last_incarceration_time[last_incarceration_time > 1]
dim(ever_incarcerated_times)## [1] 9 2# Extract demographic information for ever incarcerated agents
ever_incarcerated_ids <-
unique(agent_dt[id %in% ever_incarcerated_times$id, id])
ever_incarcerated_info <- agent_dt[id %in% ever_incarcerated_ids,
.SD[.N, list(
id,
age = last(age),
race = last(race),
female = last(female)
)],
by = id]
# Compute distributions
## mean age
age_summary <- ever_incarcerated_info[, .(mean_age=mean(age),
min_age=min(age),
max_age=max(age)
)
]
sex_dist <-
ever_incarcerated_info[, .N, by = female][, .(
Sex = c("Female", "Male"),
Count = c(N[female == 0], N[female == 1]),
"Proportion of ever incarcerated" = round(N / sum(N), 2)
)]
print(sex_dist)## Sex Count Proportion of ever incarcerated
## 1: Female 2 0.78

.(Race = race,
Count = N,
Proportion = round(N / sum(N), 2)
)
]
race_dist[]Thus, 9 persons have been incarcerated at least once. The proportion of persons who have been ever incarcerated is 0.0086455.
Now let us compute the number of females and males whoa have ever been incarcerated, and the proportions by race (% of White, Black, …)
first_tick_race_sex <-
agent_dt[, .SD[1], by = id][, .(
ID = id,

Count = c(N[Female == 1], N[Female == 0])) ]
print(sex_count)## Sex Count
## 1: Female 548
## 2: Male 493# Count number of individuals in each race
race_count <- first_tick_race_sex[, .N, by = Race][,
.(Race, Count = N)]
print(race_count)## Race Count
## 1: White 764
## 2: Asian 38
## 3: Hispanic 166
## 4: Black 73Thus, the distribution of ever incarcerated persons by sex is
cbind(sex_count$Sex, round(as.numeric(sex_dist$Count/sex_count$Count), 3))## [,1] [,2]
## [1,] "Female" "0.004"
## [2,] "Male" "0.014"The distribution of ever incarcerated persons by race is:
