Statistici ale preturilor chiriilor

  • Garsoniere

  • Apartamente 2 camere


  • Apartamente 3 camere



  • Apartamente 4 camere


In paralel cu anunturile de vanzare, in luna septembrie am inceput sa preiau si anunturile de inchiriere. Intra in calcul anunturile care au pretul situat intre 200E/luna si 5000E/luna.
Pretul mediu este rezultatul mediei aritmetice a peturilor dintr-o editie.
Pretul median reprezinta valoarea situata la mijlocul seriei de preturi ordonata crescator, spre exemplu daca sint 5 anunturi cu preturile 

2000, 2500, 2200, 3000, 1500
Asezam numerele in ordine crescatoare : 

1500, 2000, 2200, 2500, 3000

Iar valoarea mediana este 2200
Practic inseamna ca dintr-un numar de anunturi, jumatate au pretul sub valoarea mediana, jumatate peste.

Indicele Colliers - Evolutie 2005 - 2008

Reprezentarile grafice ale celebrului indice Colliers BREI cu ale sale doua componente BREI-NOU si BREI VECHI sint destul de rare in presa. Am pus cap la cap cifre publicate in diferite ziare si am obtinut graficul evolutiei preturilor din 2005 pana in prezent, asa cum reiese din statisticile Colliers.
Intrucat BREI total nu prea este facut public, am dedus metoda de calcul din cei doi indici componenti. BREI = (Brei-vechi x 1.85 + BREI-nou) / 2.85. Am dedus aceasta formula din datele facute publice pentru lunile ianuarie-aprilie 2008 pentru care avem toti cei trei indici.

Graficul rezultat :

Update 25.10.2008

Am renuntat la tabelele jpg pentru tabelele google gadgets. Pentru IE trebuie sa aveti grija sa aveti setat third party cookyes "enabled" la internet options>privacy>advanced altfel nu veti putea vedea graficele. Valorile pentru fiecare punct al graficului se por afla punand cursorul mouse-ului deasupra punctului respectiv.

Metoda de calcul

Anunturile sint preluate de pe site-ul anuntul.ro (in limita timpului pe care il am disponibil ) de 3 ori pe saptamana. Intra in calcul doar cele care contin suprafata apartamentului si pretul de vanzare si raportul dintre pret si suprafata se afla intre 500E/mp si 5000E/mp.

Am inceput sa calculez mediile pe data de 20 iunie, statisticile au fost publicate pana acum aici.

  • Media pe editie este calculata ca medie aritmetica a anunturilor dintr-o editie;
  • Media lunara pentru fiecare tip de apartament este calculata ca medie aritmetica a tuturor anunturilor publicate intr-o luna pentru acel tip de apartament;
  • Media lunara generala este calculata ca medie ponderata intre mediile lunare pe tipuri de apartamente in functie de numarul de anunturi publicat pentru fiecare tip de anunt in parte;
Cam atat pentru acum
