family's lifestyle and housekeeping would be relatively easy. If, on the other hand, a family moved into a larger home the increase area and furnishings would be much more difficult to manage without labor-saving devices. Examples of modern conveniences at that time included: Kitchen sinks with tap water hot and cold running water and wastewater drainage The addition of bathrooms as separate rooms with sinks and toilets, also with waste water and sewage drainage A furnace, also identified as a significant cost savings Closets in bedrooms, bathrooms, hallway for linen, broom closets Gas lighting, stoves and fireplaces, where gas was available Icebox or refrigerator 20th century The homes of the 20th century are much bigger than the homes of our family members from the 19th century, both in terms of square footage and number of rooms. Homes built at the beginning of the 21st century have 2-3 times more rooms than homes at the turn of the 20th century. In terms of square footage, new homes built in 2000 are 50% larger than a home built in the 1960s. The 20th century also enjoyed a proliferation of home appliances like washing machines, dryers, dishwashers, microwave ovens, frost-free refrigerators, water heaters, air conditioning, vacuum cleaners, and irons. Electricity and innovative electronics products including stereo equipment, color television, answering machine, and video cassette recorders also facilitated modern life. 21st century Comparison of modern conveniences in new housing construction In his 2011 book America's Ticking Bankruptcy Bomb: How the Looming Debt Crisis Threatens the American Dream—and How We Can Turn the Tide Before It's Too Late, Peter Ferrara says that the residential access to modern convenience is markedly different in the 21st century compared to the beginning of the 20th century: Upcoming technological advancements David Kirkpatrick, author of The Facebook Effect (2010), wrote in an article called Tech Targets the Third World projects that technological advancements in education and health care, mobile computing and broadband will empower the poor and provide economic opportunities that they would not otherwise have access. These technologies are relatively easy and cost-effective to implement because of technological advancements that have driven down the costs and because developing countries do not have expensive and outdated legacy systems to manage emerging technology.
