1990 (MCMXC) was a common year starting on Monday of the Gregorian calendar, the 1990th year of the Common Era (CE) and Anno Domini (AD) designations, the 990th year of the 2nd millennium, the 90th year of the 20th century, and the 1st year of the 1990s decade.
Important events of 1990 include the Reunification of Germany and the unification of Yemen,[1] the formal beginning of the Human Genome Project (finished in 2003), the launch of the Hubble Space Telescope, the separation of Namibia from South Africa, and the Baltic states declaring independence from the Soviet Union amidst Perestroika. Yugoslavia's communist regime collapses amidst increasing internal tensions and multiparty elections held within its constituent republics result in separatist governments being elected in most of the republics marking the beginning of the breakup of Yugoslavia. Also in this year began the crisis that would lead to the Gulf War in 1991 following the Iraq invasion and the largely internationally unrecognized annexation of Kuwait. This led to Operation Desert Shield being enacted with an international coalition of military forces being built up on the Kuwaiti-Saudi border with demands for Iraq to peacefully withdraw from Kuwait. Also in this year, Nelson Mandela was released from prison, and Margaret Thatcher resigned as Prime Minister of the United Kingdom after more than 11 years.
1990 was an important year in the Internet's early history. In the fall of 1990, Tim Berners-Lee created the first web server and the foundation for the World Wide Web. Test operations began around December 20 and it was released outside CERN the following year.[2] 1990 also saw the official decommissioning of the ARPANET, a forerunner of the Internet system and the introduction of the first content web search engine, Archie, on September 10.[3]
Due to the early 1990s recession that began that year and uncertainty due to the collapse of the socialist governments in Eastern Europe, birth rates in many countries stopped rising or fell steeply in 1990. In most western countries the Echo Boom peaked in 1990; fertility rates declined thereafter.[5]

The Global Warming Solutions Act of 2006 (AB 32) requires that CARB determine the statewide greenhouse gas emissions level in 1990. The act also requires that the Board approve a statewide greenhouse gas emissions limit, equal to the 1990 level, as a limit to be achieved by 2020. This limit is an aggregated statewide limit, and is not sector- or facility-specific. The 2020 GHG emissions limit is 431 million metric tonnes of carbon dioxide equivalent (MMTCO2e). In 2016, Senate Bill 32, California Global Warming Solutions Act of 2006: Emissions Limit. (SB 32) further requires California to reduce statewide GHG emissions to 40% below the 1990 level by 2030.
Calculation of the original 1990 limit approved in 2007 was revised in 2014 using the scientifically updated Intergovernmental Panel on Climate Change (IPCC). Fourth Assessment Report (AR4) global warming potential (GWP). values, to 431 MMTCO2e. The Board approved 431 MMTCO2e as the 2020 emission limit with the approval of the First Update to the Scoping Plan on May 22, 2014.
The staff report titled "California 1990 Greenhouse Gas Emissions Level and 2020 Emissions Limit" discusses the original development of the 1990 statewide emissions level and provides a summary of the key emissions sources, the methodologies used to calculate the emissions, and the sources of data. These methods use the original IPCC second assessment report GWPs.

The 1990 census asked only seven population and seven housing questions. A sample of respondents received the "long form," which included 23 more population inquiries. The 1990 census collected the following information, listed by question number:
Results: In 1990, 1,429,577 abortions were reported -- a 2.4% increase from1989. The abortion ratio for 1990 was 345 legal induced abortions per 1,000live births, and the abortion rate was 24 per 1,000 women ages 15-44 years.Most women undergoing abortions were young, white, and unmarried; most hadhad no previous live births and were having the procedure for the firsttime. Approximately half of all abortions were performed before the 8thweek of gestation, and 87% were before the 13th week of gestation. Youngerwomen were more likely to obtain abortions later in pregnancy than wereolder women.
Interpretation: Since 1980, the national number (and rate) of abortions hasremained relatively stable, with only small (less than or equal to 5%)year-to-year fluctuations. However, since 1984, the national abortion ratiohas declined; in 1990, the abortion ratio was the lowest recorded since1977. Increasing rates of childbearing may account for some of thisdecline.
For 1990, DRH compiled data received from 52 reporting areas: 50states, New York City, and the District of Columbia. The total number oflegal induced abortions was available from all reporting areas, most ofwhich provided information about the characteristics of women obtainingabortions. For 46 reporting areas, data were provided from the centralhealth agency *; for the remaining six reporting areas, data were providedfrom hospitals and other medical facilities. Data were reported by thestate in which the abortion occurred.
