Fetch Michigan enrollment data — fetch

Downloads and processes enrollment data from the Michigan CEPI MI School Data headcount files.

Usage

fetch_enr(end_year, tidy = TRUE, use_cache = TRUE)

Arguments

end_year: A school year. Year is the end of the academic year - eg 2023-24 school year is year '2024'. Valid values are 1996-2025.
tidy: If TRUE (default), returns data in long (tidy) format with subgroup column. If FALSE, returns wide format.
use_cache: If TRUE (default), uses locally cached data when available. Set to FALSE to force re-download from CEPI.

Value

Data frame with enrollment data. Wide format includes columns for district_id, campus_id, names, and enrollment counts by demographic/grade. Tidy format pivots these counts into subgroup and grade_level columns.

Examples

if (FALSE) { # \dontrun{
# Get 2024 enrollment data (2023-24 school year)
enr_2024 <- fetch_enr(2024)

# Get wide format
enr_wide <- fetch_enr(2024, tidy = FALSE)

# Force fresh download (ignore cache)
enr_fresh <- fetch_enr(2024, use_cache = FALSE)

# Filter to specific district (Detroit)
detroit <- enr_2024 |>
  dplyr::filter(district_id == "82015")
} # }
