D1 Stratification, shock and mobility

Topic

Four indicators cover two distinct fronts within the "Socioeconomic Behavior" track: a structural front—encompassing stratification and mobility—and an acute shock front, which activates when an exogenous event strikes the population. Both fronts are necessary because they measure different things: the exogenous shock to the population is measured by the simultaneous decline in labor force participation and public health indicators, whereas political radicalization is measured by the persistent gap between expected mobility and realized mobility.

Socioeconomic status and education indicators measure the population's distribution by stratum and its aggregate educational level; their evolution relative to the cost of living determines whether the track is in a regime of expansion, polarization, or mobility stagnation.

Labor force participation measures the fraction of the working-age population that is actually employed or seeking employment; a sharp, sustained drop in this figure—alongside the deterioration of public health indicators—serves as a direct signal of an exogenous shock affecting the population.

Public health indicators measure mortality, morbidity, and healthcare system capacity; a sudden deterioration in these metrics—coupled with the decline in labor force participation—directly measures the exogenous shock to the population. This same anomaly propagates to the other five tracks through the previously identified entry points.

Perception and confidence surveys measure the gap between expected mobility and realized mobility; when this gap persistently crosses a critical threshold, it triggers political radicalization driven by economic frustration—an anomaly that shifts that frustration from the economic sphere into the realm of political activity.
