Obiectivul : Ne propune sa analizam efectivul populatiei la nivelul fiecarui judet
Datele disponibile pe platforma INSS oferă informații cu privire la numărul și structura populatiei Romaniei, in perioada 2012 - 2025, pe teritoriul României.
Structura setului de date descarcat de pe site-ul INS este:
Efectivul populatiei este determinat fie la nivelul României, fie, în funcție de structura administrativ teritorială, la nivelul județelor etc., la nivelul regiunilor de dezvoltare economica (macroregiuni, regiuni de dezvoltare etc.) etc.
Observam ca la nivelul Romaniei, in anul 2025, au fost inregistrate un numar de 19.043.151 persoane.
Romania este organizata, din punct de vedere administrativ-teritorial, in sate, comune, orase si judete. In prezent, Romania are 42 de judete, 8 regiuni de dezvoltare si 4 macroregiuni.

Observam ca Bucurestiul prezinta cea mai mare populatie, respectiv cel mai mare procent din totalul populatiei inregistrat la nivelul Romaniei.
