Geographic mobility flows by province

Thus, with respect to the group of salaried workers in a province i, the following concepts will be defined:

The periods of employment in the labor market between year ty (t-1) can be classified, in turn, taking into account the province of tax residence in the reference year and in the previous year. In this sense, for a particular province, and in the reference year t, the Labor Market of that province i may come from the following movements of salaried workers:

• Stay in province i (Pure Stay)

In year t the salaried worker is part of the Labor Market of province i and in year (t-1) he has also been part of the Labor Market of that same province i.

• Inflows to province i

Situation determined by the incorporation in year t of an employee to province i from another different province j, that is, in year (t -1) he is not part of the Labor Market of province i and is part of the Labor Market of province j, and in year t he ceases to be part of the Labor Market of province j and becomes part of the Labor Market of province i. Depending on whether the province j of origin belongs to the same Autonomous Community as the destination province i, the following inflows are distinguished:

• • Equal Autonomous Community

The destination province i and the origin province j belong to the same Autonomous Community. In the view by Autonomous Community, this movement is recorded as a pure permanence.

• • Different Autonomous Community

The destination province i and the origin province j belong to different Autonomous Communities. In the view by Autonomous Community this movement is recorded as an inflow to the Autonomous Community to which the destination province i belongs, at the same time a change of province and Autonomous Community occurs.

• Outflows from province i

This situation occurs when the employee in year (t-1) was part of the Labor Market of province i and in year t becomes part of the Labor Market of a different province j, ceasing to belong to the Labor Market of province i. Depending on whether the province i of origin belongs to the same Autonomous Community as the destination province j, the following outflows are distinguished:

• • Equal Autonomous Community

The destination province j and the origin province i belong to the same Autonomous Community. In the view by Autonomous Community, this movement is recorded as a pure permanence.

• • Different Autonomous Community

The destination province j and the origin province i belong to different Autonomous Communities. In the view by Autonomous Community this movement is recorded as an outflow from the Autonomous Community to which the province of origin i belongs, at the same time a change of province and Autonomous Community occurs.

Taking into account the above definitions, the following relationships must be fulfilled:

The sum of the outflows from the provinces of the same Autonomous Community in year (t-1) must be equal to the sum of the inflows to the provinces of that same Autonomous Community in year t.

The sum by provinces of the outflows (or inflows) to provinces of different Autonomous Communities coincides, for each Autonomous Community, with the outflow (or inflow) in the Autonomous Community view.

For each Autonomous Community, the sum of the pure permanence of its provinces plus the flows in (or out) to provinces of the same Autonomous Community coincides with the pure permanence in the vision of Autonomous Community.

For each province, the number of salaried workers who are part of the Labor Market in year t must therefore be equal to the number of new hires in year t in that province, plus the number of pure stays in the province in year t, plus the number of inflows to the province from provinces of the same Autonomous Community in year t, plus the number of inflows to the province from provinces of a different Autonomous Community in year t.

For each province, the number of salaried workers who are part of the Labor Market in year (t-1) must be equal to the number of Discharges that occurred in year t in that province plus the number of Pure Remains in the province in year t, plus the number of Outflows from that province to provinces of the same Autonomous Community in year (t-1), plus the number of Outflows from that province to provinces of a different Autonomous Community in year (t-1).

Salaried workers in province i year t = (1)_Yo+(2)_Yo+(3)_Yo+(4)_Yo

Salaried workers in community i year t-1 = (4)_Yo+(5)_Yo+(6)_Yo+(7)_Yo
