spread out

These changes have come on gradually as the city center and the resulting "heat island" have gotten more built up and more spread out. In 1972 temperatures in the hottest part of downtown were 6 to 9 degrees higher than in the surrounding countryside.

According to Digitalcity, New York's e-zine of digital age business and culture, there are now more than 1,100 Silicon Alley companies in Manhattan south of 41 st Street; another 450 in Midtown; and 571 spread out throughout the rest of Manhattan.

"Geographically, we've spread out in areas where there is going to be increased govermuent work as well as renovation and rehabilitation, " said Kiri Borg, directorof Business Development for Tishman Interiors.
