2004). Delhi lies about 300 m above the sea level. Fig. 1 depicts the
Delhi administrative boundary (with circular boundary) and 10 km
buffer considered. The buffer region is expected to reveal the
sprawl trend which helps in visualizing the likely urban growth in
the region. The National Capital Territory (NCT) of Delhi is spread
over an area of 1484 sq km and the Delhi metropolitan area lies
within NCT. The NCT has three local municipal corporations:
Municipal Corporation of Delhi (MCD), New Delhi Municipal
Council (NDMC) and Delhi Cantonment Board (Debnath and
Eugene, 2004). The central Delhi is considered as central business
district and consists of many industrial and residential areas and
Delhi Fort and Jumma masjid are famous monuments found in
Central Delhi. The Rastrapathi Bhavan, Parliament House and Supreme
Court of India etc. are also located in New Delhi.
Fig. 2 and Table 1 portray the population growth of Delhi during
1901e2011. Table 1 reveals that the population density has
increased from 1207 (1970) to 5726 (2011) persons per sq.km. The
FDI inflows to Delhi during the period 2000e2006 were found to be
Rs.318.61 billion. The total FDI inflows into Delhi is about US$ 20.1
billion according to Economic survey of India. The intensify growth
of economy and higher per capita income within the urban district
have influenced the real estate’s business resulting hike in the costs
of land and cost of living..
