The Irish community is one of New York City's major and important ethnic groups, and has been a significant proportion of the city's population since the waves of immigration in the late 19th century. As a result of the Great Famine in Ireland, many Irish families were forced to emigrate from the country. By 1854, between 1.5 and 2 million Irish had left their country. In the United States, most Irish became city-dwellers. With little money, many had to settle in the cities that the ships landed in. By 1850, the Irish made up a quarter of the population in Boston, New York City, Philadelphia, Buffalo, and Baltimore. Today, Boston has the largest percentage of Irish-Americans of any city in the United States, while New York City has the most Irish Americans in raw numbers. During the Celtic Tiger years, when the Irish economy was booming, the city saw a buying spree of residences by native Irish as second homes or as investment property. History Irish Americans (most of whom are Irish Catholic) make up approximately 5.3% of New York City's population, composing the second largest non-Hispanic white ethnic group. Irish American Protestants first came to America in colonial years (pre-1776).The largest wave of Catholic Irish immigration came after the Great Famine in 1845. Most came from some of Ireland's most populous counties, such as Cork, Galway, and Tipperary. Large numbers also originated in counties Cavan, Meath, Dublin, and Laois. In the Civil War, the massive anti-draft riots of 1863 represented a "civil war" inside the Irish Catholic community, according to Toby Joyce. The mostly Irish Catholic rioters confronted police, soldiers, and pro-war politicians who were often leaders of the Irish community. In the "early days", the 19th century, the Irish formed a predominant part of the European immigrant population of New York City, a "city of immigrants", which added to the city's diversity to this day. After they came, Irish immigrants often crowded into subdivided homes, only meant for one family, and cellars, attics, and alleys all became home for the poorest immigrants. As they accumulated wealth they moved into better housing. Bay Ridge, Brooklyn, was originally developed as a resort for wealthy Manhattanites in 1879, but instead became an upscale family-oriented Italian- and Irish-American community. Another large Irish-American community is located in Woodlawn Heights, Bronx, but Woodlawn Heights also has a mix of different ethnic groups. Conditions were
