Changes in version 0.1.0 (2026-07-23)                  

  - Initial CRAN release.
  - Added functions for basic demographic analysis: fertility
    (dem.fert), mortality (dem.cdr, dem.mmr, dm.chm), and life tables
    (lifetable, lifetable_nqx).
  - Implemented mathematical population projection (math_project), a
    stochastic simulation-based projection (project_population), and
    demographic interpolation models (interpolation, karup_king,
    brass_logit).
  - Addressed CRAN reviewer feedback:
      - Formatted description and references in the DESCRIPTION file to
        match CRAN rules.
      - Suppressed all raw console printing in core demographic
        functions and implemented custom S3 print methods
        (print.dem_cdr, print.dem_fert, print.dem_mmr, and
        print.dem_chm) to align with standard R package behavior.
      - Added academic references to the documentation blocks of all
        core R files.
      - All invalid links have been removed from the documentation and
        Description file.
  - Methodological corrections prior to release:
      - brass_logit() now uses the correct inverse of the Brass
        half-logit transform, exp(2Y)/(1 + exp(2Y)), and documents that
        its input is the cumulative probability of dying q(x) = 1 -
        l(x).
      - lifetable_nqx() and lifetable() now account for the width of
        each age interval (1, 4, 5, ... years) when computing nqx and
        person-years lived (nLx); lifetable() gains sex and radix
        arguments and uses Coale-Demeny separation factors for ages 0
        and 1-4.
      - karup_king() defaults now work out of the box (packaged
        Karup-King coefficient matrices).
      - project_population() now propagates all simulated trajectories
        through the projection horizon and reports lower quartile,
        median, mean, and upper quartile per year; net out-migration now
        reduces growth.
      - dm.chm() neonatal filter now uses age < 1 month.
      - Removed unused dependencies (tidyverse, brms, logger,
        data.table) and leftover Stan scaffolding.
