Downtown Brooklyn is becoming the new Manhattan, according to one advocacy group's report.

The Downtown Brooklyn Partnership says a new study found that fresh development in the neighborhood over the past decade garnered private investments of around $10 billion.

Major projects include the Barclays Center, which attracted the Nets and Islanders, the Brooklyn Academy of Music, which in turn created a new cultural district, and hundreds of millions of dollars in infrastructure upgrades, according to Tucker Reed, the Partnership's president.

Crime is also dramatically lower in the NYPD's 84th Precinct compared to just a few decades ago, Reed says.

The Partnership says it wants to evaluate schools, open spaces and other services in the neighborhood to promote continued growth.
